...and this is why I love reading posts in this forum.

Genuine people helping others.

Good work on the bike, looking forward to the next installments!

another quick update to feast your peepers on !

you may have seen another post with a worried little me concerned about a pulse / clunk on the transmission when the bike was on the stand and in gear.

as the headers were off it was deemed sensible to remove the sump and get an eye full of the bits that turn around.

this is a close up of the filter in the sump, on this model they cant be taken apart but it was intact and in good condition so it was pulled out.

Next to come off was the clutch basket

this is the intact unit with the cover off

after the spider and bolts are removed it really isnt clear how to remove the retaining nut

eventually I was convinced that pushing a flat head screwdriver into the big drive sprocket was a good idea to provide enough force to undo the nut. after cries of trepidation the nut was easily removed (of course)

The next step was to remove the bearing, i didnt get any pics of this but all you need to do is use pinch pliers to grip the bearing either side and pull it out.

Finally with the basket off you can see through and get a reassuring look at everything, all was well

now to inspect the gears

http://i874.photobucket.com/albums/ab307/JDHunter83/engine/AA1C48D1-0C8E-4FCF-9050-398C433C9683_zpskw84zpwl.jpg

With me cranking over the engine with a ratchet on the impulse ignition generator nut Alan stuck his head under the transmission and visually inspected each cog (after wiping oil from his glasses several times) and went through the gears making positive sounds. I also don't have the priceless picture of my face when the engine hissed on each revolution as i cranked it over without the oil in (I'm also learning not to react when i am the butt of northern jokes about my engine must have imploded). again all seemed fine so time to put it back together.

After everything has been put back together and the oil put back in its rightful place it was back to concentrating on the misfire after the new pipes have been installed.

I will ride this bike within a week even if its rolling down a road with the engine off !.

Collector to linkpipe adapter is being made tomorrow and should arrive on Friday hopefully. If you want it back together tomorrow with old system, you'd best put it at side of bike tomorrow morning mate

wahooo friday !!! this might come together you know

I neglected to add that my bargain can not only had been hacked to pieces but also wasnt the correct size

[mattycoops43]

Be aware that a stainless system will sound a bit more 'tinkly' than a mild steel system, the engine is not broke, it is to do with the nature of the stainless. You ill hear noises you haven't heard before. Partly cos stainless will be thinner to do the same job.

thats an interesting point.

[megawatt]

There's tinkly and fookin rattly Jamie. I still think it needs a rebalance.

are we talking about me or the bike ?

rebalance with the new cool exhaust system together and we might even go for a ride out !! My other half is convinced i have sold the bike because it hasnt been here for weeks.

[Hunter]

a bit more of an update on the bike..

After buying the bargain end can it turned not be a complete bargain as the link pipe had been abused and had to be cut short. This had a double negative of creating a loose fit and pulling the can in too tight which means it was touching the swing arm.

Problem solved by Mr Mega and a link pipe adaptor so perfectly made it sealed without a gasket.

Sorry about the dirty bike, the stainless headers were perfect and clean before going out in the horrible storm but hey i couldn't resist a ride.

with the new can on

as you can see it hangs just right as it were !

[Hunter]

So after the nice new exhaust she runs even worse with surging and lack of go below 7k and a lot of popping every time i roll off. I was expecting this having put essentially a straight through system on the bike so the next major job will be a carb clean and re-jet.

It is probable (apparently) that it is running lean which might be smoothed out by the adjusting the mixture screw.

All of that said it does start, idle and sound like a different bike. I really am happy to just get on and ride until the performance bothers me enough.

a few more pics that aren't that interesting or good but still.

This is the rubber cover for the coils. Depending on if you believe the stuff on forums this can cause a loss of 10bhp as they air box is sucking hot air straight off the head. I'm not inclined to believe it but it should at least stop crap resting on top of the coils.

Again all credit to Alan who has been a shoulder to cry on and a constant source of P taking.

[Hunter]

a quick vid with a few revs, i live on a farm in the arse end of nowhere but there are a few other people who live here as well so i dont like sitting there revving away too much.

its only 3k revs but still sounds excellent

[Hunter]

ok a bit of an update.

everything has been great with the bike and Alan has been just awesome for putting up with my heap of crap and getting / keeping me on the road.

So after riding it from kent to wiltshire and back I was really happy with the bike and decided to do valve clearances etc.. ( I say me I mean Megawatt). I did a quick coolant flush today and noticed oil in the coolant, i then noticed bubbles in the expansion tank. Great that will be the head gasket then. there is no milky mess in the oil or coolant so hopefully i caught it early but i will have the head skimmed any way. so i stripped off the carbs to put in the dynojet main jets and decided to pull the spark plugs to find oil on the threads.

I'm not sure if this is actually oil (i am reasonably confident) but if it is I guess it is either the rocker valve gasket or worn rings etc...

some pics are below but megawatt will no doubt be speeding round with a trailer at some point

http://i874.photobucket.com/albums/ab307/JDHunter83/plugs/IMG_0468_zps14f587df.jpg

any ideas ?

[Stu]

does look like rocker gaskets to me due to the fact there is none on the electrode

the electrode is a nice dry soot and not oily

I hope your right,another £35 to throw in the bucket then, still better than rings etc.. i think i new engine would be cheaper.

I think it shows a little lean which is correct given the popping when i decelerate.

hey hunter, nice bike there, i really like those 600's.

good to see members helping each other out. nice one megawatt.

I'll keep my eye on this thread

[Hunter]

So it continues

I found an engine ! - somewhere north of london (clapham feels like the north to me) i picked up an F3 engine with half the miles of my current F2

so it was shoehorned into the boot

http://i874.photobucket.com/albums/ab307/JDHunter83/Mobile%20Uploads/4DEA0E07-FA1A-4CBF-86F4-9A934137845D_zpsv2a6hyr4.jpg

http://i874.photobucket.com/albums/ab307/JDHunter83/Mobile%20Uploads/E1A46358-D564-4AB8-8E8A-41A1264AF292_zpskcfo9oon.jpg

it was then over to megawatt's brand new garage seemingly custom built for my bike to start the transplant.

[Hunter]

With the fairing off the next item was the exhaust

http://i874.photobucket.com/albums/ab307/JDHunter83/Mobile%20Uploads/5218C911-F8C2-4219-A659-6F37F149EF4E_zpsbkt2vuwo.jpg

The all cables and most of the bolts were removed and after a lot of jiggling and a minor hand fracture it was out

http://i874.photobucket.com/albums/ab307/JDHunter83/Mobile%20Uploads/800BF624-CE77-4739-98CE-1212866A3332_zpsj0w7gsxw.jpg

So i spent some time checking over the new engine and decided to pull the plugs and found this

http://i874.photobucket.com/albums/ab307/JDHunter83/Mobile%20Uploads/CB508FFF-F994-464A-9080-353E4401D7B1_zps3o4aiq1v.jpg

Surely not oil on the plugs again ! am i cursed or do I just worry too much ?.

So after I have helped alan tomorrow to felt my garage / sorry his garage built for my bike we are going to pressure test the engine. If its junk then I will be throwing it back at the seller.

[Hunter]

well this project continues, i have had problems removing photos from my phone and uploading to photobucket so haven't updated for a while.

After the valve cover bolt snapped in the cylinder head of the new engine (it passed compression test) it has become a bit of a rebuild with everything from new shock and powder coating to head gasket and valve clearances.

I will update some more soon but with the engine not back in the bike yet it has my full attention...watch this space..

Get the photobucket iPhone app and you can import them then.

I have it but my iphone has decided it doesn't really like to do anything other than operate as a device for calling people and a as very average torch.

Windows phone has to be better right .....

Google Nexus5 is the best phone ever. Great camera, un-scratchable screen, and with Google plus all photos are automatically backed up to the internet ready to share.

Hi Guys,

Ken from BikeBuilds.net here. Those F2s are great little bikes. I had a new '94 back in the day and loved it.

We were glad to add Hunter's bike to our database: http://www.bikebuilds.net/honda-cbr-600-f2-build-by-hunter
