Tomorrow Sunday 20th ,Rugby town centre. Meet at Truckstop on A5 for ride in at 10am. https://www.therugbytown.co.uk/homepage/10019/rugby_bikefest

Heights do it for me aswell,mainly cliff edges. Cause of this was my youngest daughter. We were on holiday around Swanage when she was about 7 years old,went for a walk around Durlston park . On a cliff top walk she was walking behind us in a mood,I turned around to find her stood on top of a low wall with a 100ft drop down to the sea. I had to gently walk back and lift her to safety. Even now just seeing cliff edges on tv or films makes me cringe.

Welcome aboard. How long has the bike been stood up,just over the winter? Assume it was running ok when you last rode it? A few things I'd check; Has the choke mechanism stuck,gummed up Throttle slides all moving freely.Throttle cable free. Carbs overflowing,stuck float valves. Inlet rubbers not perished or gone hard. Air filter ok. Presume all the basics; points,ign timing and valve clearances all ok? When I were a lad in the 70's a guy in our village had a 400/4 with an aftermarket exhaust,you could hear him miles away redlining the thing

The dickhead in a bmw that was in the wrong lane at a roundabout at junc15A of the M1 and instead of going left decided to carry on around , I nearly stoved into the side of him,had I not anticipated what he might do and slightly held back. I have had this happen at the same roundabout before in my car so that sixth sense kicked in and I was ready for him. Last time in my car,the other car cut across my front and I had to swerve right and do another lap of the roundabout. Numptys.

+1 on this,there are plenty of poor quality bearings around. Buy from a reputable source. We will only use SKF at work from bitter experience.

That's a great photo and interesting family history. You can see that era of bikes at the Banbury run in June. Normally 600 odd bikes present and a sight to see them tackling Sun rising hill. http://www.banbury-run.co.uk You can see the bikes reg no so someone from the club could help trace if its still around?

Anyone going to JHC this Friday?

His shed and buried shows would be more tolerable if they just kept it factual instead of trying to be funny with his beardy sidekick. Too much like Clarkson era Top Gear,old blokes larking around.,not funny,just sad .

Shhh ! Keep it to yourself, he is all powerful. He has eyes and ears everywhere. His disciples will come for you in the night . No they wont,they will be too busy wetting their pants over his latest "fantastic" album.

Total dross. Same as Adele.

You shouldnt be cranking it without any oil in,you will damge the crank and cam bearings,these will be the first to suffer. If you lubed the pistons and bores properly during assembly,these should be ok for a short burst of cranking. If that is the oil pick up pipe,dont try cranking any more until that is back in place,you will fk your engine. Its worth priming the oil pump while its upside down aswell so it draws the oil up right away. When you are carrying out the comp test,do you continue cranking until the pressure stops rising,it will take a few revolutions of the engine to achieve full pressure. You have got a one way valve (usually a schrader),ie when you stop cranking the pressure remains at 100 psi or whatever it achieves and you have to press a button to release it?

Buy something your son wants,not what you think he would want. Friend of mine,heavily into vespas bought one for his 16 yo lad,not interested one bit. When I bought my eldest daughter her first car,old type of Corsa,there was no "oh wow thanks Dad",she said "it's a bit rusty isn't it".She did get to love the car though. Teenagers; tricky things.

I work in Northampton and the roads around there are in a shocking state. I have reported numerous craters on my route into work and between Rugby and Daventry,but don't hold out much hope,Northants council has run out of money. On the A5 near Dav,there is a crater in the centre of the road about 6 ft long and looks about 4 inches wide,not enough to trouble a car but would surely have a motorcycle over.

What inlet pressure does your set recommend? On our Snap On set we use airline pressure in the shop,about 6bar. Yes very good at diagnosing where any issues lie.

On the gauges,the left hand is the supply pressure,its only 2 bar?

Exhaust clean? The inside not the outside BTW. 2 strokes are fussy about exhaust back pressures.

Yes you can dress it with a bearing scraper,not something an inexperienced hand should attempt though. If a bearing is seriously scored it should be replaced,crank polished or ground with appropriate sized shells and the cause of the scoring investigated. You sat polish the scratches,do you mean scratches in the shell or journal?

I tell you what mate, your bolt keeping method is spot on. When I did my ZXR I just chucked everything in a magnetic tray and trusted my memory. I do the same,bit of cardboard,draw the shape of the casing and poke the bolts through in the correct location.

Surely if you remove shallow scoring with wet and dry this means effectivly lowering the surrounding surface to match the depth of the scoring. Would this not increase the likelihood of excessive play in the bearings ? I am by no means an expert but I would have thought that a little scoring might be better left alone. I am keen to know what the thinking is here . PS do you mean the shells rather than the caps ? It is acceptable to lightly polish crank journals with very fine abrasive tape to clean it up,spun up in a lathe.However,as you say removing too much will increase the bearing clearances so best left to someone experienced I'd say.You would need to measure the journals with a micrometer to check if they are still in spec.Any deep scores in the crank will not necessarily scrap it but again someone with experience would need to say what is acceptable. Under no circumstances touch the bearing shells with abrasive.The outer layer (white metal) is very soft and you will easily damage it or impregnate it with particles of the abrasive. To check the bearing clearances,you can use a product called plastigage.Basically a thin plasticene roll squashed between crankshaft and rod or main bearing,the less clearance,the wider the plastigage is spread.Don't know in particular what clearances on the Triumph are but 0.038 to 0.050 mm on a big end would sound about right.Any more and the oil film cannot support the load and it will hammer the bearing.This would be a heavy knocking sound rising with engine speed. This would be the clicking test MW refered to. Judging from the pics,the bearings looked ok with just normal running marks that go with the age of the engine.

Second ring aswell. Could be the bores worn as much as the rings,measuring ring gaps will tell you if there is wear but not where.Would need a bit of kit like this to measure them. https://www.ebay.co.uk/itm/Metric-Dial-Bore-Gauge-50-160MM-0-01MM-Bridge-Cylinder-Internal-Bore-Measuring/273050023547?hash=item3f930cb67b:g:KboAAOSwlpZacr5h Need to check the finish in the bores aswell,is there any honing left? If everything measures up ok, it may just need a flickhone of the bores and new rings?

11Kw is about 14hp,good luck with that in a road going 50cc. My RGV250 supposed to make about 60hp so a fifth of that is 12hp. The RGV can only achieve this with massive exh ports and 2 stage power valves,if it didnt have these it would be unrideable on the road,powerband is only about 2500rpm as it is. By all means have a go at tuning it,I know I did when a yoof, but dont expect high power,rideability and reliability to go hand in hand.

As above,know when to cut your losses before you spent more on it than you would recover. Used motors on the bay starting at £200-400,pick one that has some kind of warranty,fit it and sell it(which was the plan all along?) You can then sell your engine as spares.

All the dopey car drivers with auto headlights who don't think to switch them on manually when the visibility is poor but not dark enough to switch on automatically.

Doesnt appear so. https://www.ebay.co.uk/itm/2000-Triumph-Sprint-955i-RS-955-i-engine-motor-crankcase-cases/301981453628?hash=item464f7f4d3c:g:lSUAAOxyDEVScs7o

From what I can gather from net,the Triumph barrels are integral to the upper crankcase so pistons will go in from the top so a conventional ring clamp would work.. Hyabusa barrels are separate so pistons in from below hence your use of jubilee clips?
