chrisgatguis Posted February 24, 2009 Share Posted February 24, 2009 (edited) Hi all,bit of a strange one, I've got a GS 500 which as we know is no rocket however its been fast enough for me having past my test only 5 months ago..however, my friend has just bought a ER5, hes only got a A2 license so he's had it restricted by the dealer to 33bhp..Apparently he's had nearly 100 out of his restricted bike.I've got to about 90 before and it doesn't feel that there is that much left..My question is, is it possible to identify if the bike has been restricted? and would it be shown on any documents i.e. V5 doc etc?Does anyone know what performance I should be getting if the bike was standard, I've read of a top speed of 115 mph but as it stands I can't imagine it could acheive that?thankschris Edited February 26, 2009 by chrisgatguis Quote Link to comment Share on other sites More sharing options...
Korben Posted February 24, 2009 Share Posted February 24, 2009 He should have a Restrictor Certificate. Quote Link to comment Share on other sites More sharing options...
chrisgatguis Posted February 24, 2009 Author Share Posted February 24, 2009 Yeah, i'm thinking more of the guy i bought the bike off may have had it restricted, but rather than tell me when i bought it just sold it on as standard possibly?Does anyone know what the restrictor is like on a GS?

Bill_on_a_bike Posted February 24, 2009 Share Posted February 24, 2009 Reported top speeds to all tend to be a bit ambitious. Quote Link to comment Share on other sites More sharing options...
chrisgatguis Posted February 24, 2009 Author Share Posted February 24, 2009 cheers for the replies..I've found out it can be a combination of slides (or 'Pistons' in the Haynes) in the carbs which has more holes in, apparently - more holes = less of a vacuum therefore the slide doesn't move as far, AND washers between carb / engine block....I've come a cropper and just realised that my Haynes isn't the right one.Does anyone know how to remove the throttle cable? Unlike my Haynes it has two cables (one return) rather than just the one.The Cable goes round a rotating pulley, so it seems i can't easily disconnect it?Heres a pic:Top of both cables, (actually the same cable joined together) - goes round a 'pulley' below which is attatched to the carb Quote Link to comment Share on other sites More sharing options...

chrisgatguis Posted February 24, 2009 Author Share Posted February 24, 2009 WF - thanks! on further inspection you were right it IS two cables, ends of cable meet right at the bottom of pulley. slackened them, and managed to get them through!

Bill_on_a_bike Posted February 24, 2009 Share Posted February 24, 2009 Any washers? Holes in diaphrams? Quote Link to comment Share on other sites More sharing options...
chrisgatguis Posted February 24, 2009 Author Share Posted February 24, 2009 Couldn't see any washers, not taken the top of yet... update in a minute loledit: make that lots of minutes - i can't get the top covers off as the screws are stuck solid.. letting some WD40 sink in before trying again.

chrisgatguis Posted February 24, 2009 Author Share Posted February 24, 2009 No is the answer, all bits are totally fine, no washer and no extra holes in the slides...... damnit...The carbs seem in really good condition so far.. not managed to get the float bowl off yet as the screws are very hard in!

Try looking in the airbox, i believe they fitted blades to retrisct the amount of air flow...? Quote Link to comment Share on other sites More sharing options...
T180985 Posted February 25, 2009 Share Posted February 25, 2009 not much help for your problem but thought i would say my mate has a gs500 and says it should be able to reach 105mph so yours isnt far off Quote Link to comment Share on other sites More sharing options...
j_ase Posted February 25, 2009 Share Posted February 25, 2009 Just a thought is your possible lack of performance related to something else? ie a fuel restriciton or just general wear and tear... After giving my bike a full service where I changed air filter, fuel filter, plugs etc the performance was much better.... Quote Link to comment Share on other sites More sharing options...

I'll see what a good service will do. Also spoken to Ragdol, we've come up with another idea - it has a K & N on it - if the jets are still normal then it might be causing it to run lean maybe.Float bowl screws are completely stuck, can't shift them at all. already tried a few things and nothings worked - just causing the screws to shred Quote Link to comment Share on other sites More sharing options...
chrisgatguis Posted February 26, 2009 Author Share Posted February 26, 2009 Going to have to drill these awful screws out.... what a nightmare, screwdriver wasn't slipping just thoroughly eating into the head of the screw before my very eyes...hopefully i can find a screw extractor small enough to do the job. I've found a site / ebay which sells packs of screws for the carbs so replacing them isn't an issue Its just annoying that its every single one (8 all together) Quote Link to comment Share on other sites More sharing options...
Guest Posted February 26, 2009 Share Posted February 26, 2009 tip for ya for the future especially with aluminium casings such as carbs .... boiling water .. if possible immerse screws and casing into a pot of boiling water or sometimes judt pouring it around will help loosen them .... but try not to get water into carb or fuel pipes Quote Link to comment Share on other sites More sharing options...

chrisgatguis Posted February 26, 2009 Author Share Posted February 26, 2009 Took the carbs round me dads so i could use his bench drill.The screws just blunted the drill bits! Went to Halfords (not a very big one) and they didn't have the extractor. Got one from Focus DIY but its the drill bit type (looks a bit like a counter-sinking drill bit) Tried it and just actually drilled into the head of the screw.So its either new drill bits and a different Halfords for extractor set. or taking it to a bike shop to have a crack at...Bloody annoying though!

chrisgatguis Posted February 26, 2009 Author Share Posted February 26, 2009 Awesome - managed to get them out - terribly!basically used my screw extractor (on anti clockwise) which basically drilled a cone into the screw head.Then i used a punch and hammer right in the hole i had made......THEN - i basically used some plyers (the ones with a moveable handle to get maximum leverage - bit like a mole grip) to completely squash the top of the screw into an oval shape.Then back with the extractor tool and the screw just unscrewed out.Did this 8 times!! cool... just need the new screws etc to come now......On with the cleaning!
