Guest Posted October 13, 2009 Share Posted October 13, 2009 I have an AJS CR3 125, which seems to have seized.Trying to take the gear box cover off and cannot figure out how to remove the kick start. Any clues??????? Quote Link to comment Share on other sites More sharing options...
Guest Posted October 13, 2009 Share Posted October 13, 2009 normally there's a pinch bolt, like that on your gear lever, this pinches the lever onto the threaded spline, once the bolt is out, its a case of trying to get the thing off straight, pushing a bladed screwdriver into the slot and applying a little pressure spreads the sides, and helps slide the lever off..

Guest Posted October 13, 2009 Share Posted October 13, 2009 thanks, i managed to get it off and get a look and i cant see anything wrong with the engineit just wont start or do anythingand it being a 4 stroke its very difficult to get in to get a better lookthe gears and clutch move right, the valves operate properly when i turned the bolt to manually move the pistonit just wont go under its own power Quote Link to comment Share on other sites More sharing options...
Guest Posted October 14, 2009 Share Posted October 14, 2009 Engine runs???goes into gear??Then you have a clutch issue... you need to play around with the adjusters, one at either end of the cable, how long has it been like this, has the cable snapped...more information required...

Guest Posted October 14, 2009 Share Posted October 14, 2009 fuel is finetopped up monday morning and recently replaced the fuel lines and has no leaks Quote Link to comment Share on other sites More sharing options...
Guest Posted October 14, 2009 Share Posted October 14, 2009 OK, are you getting a spark at the plug... as its a kickstart you may need a willing volunteer... hold the plug on the head of the engine and kick over, if its not on the engine you will get a small electric shock...

Guest Posted October 14, 2009 Share Posted October 14, 2009 its doubtful being a 4stroke thats its seized.. does the kickstart operate as it should..? Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 the kickstart had locked up, its totally stuck Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 Looks like either the piston or the gearbox are buggered... Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 thats what i was worried aboutim going to check everything over when i get chance, its very hard to take apart though lolpiston is going to be a pain to get to Quote Link to comment Share on other sites More sharing options...
Bogof Posted October 15, 2009 Share Posted October 15, 2009 thats what i was worried about im going to check everything over when i get chance, its very hard to take apart though lolpiston is going to be a pain to get to Hold on a sec. Before you start ripping the engine apart, are you SURE it's seized, cos...everything seems to work how it should, piston, valves, gears, clutch, it all seems to work fineit just will not start and the gears and clutch move right, the valves operate properly when i turned the bolt to manually move the pistonit just wont go under its own power ...and now suddenly it won't turn over or anything? Have I missed something?Does the electric start still operate and turn the engine over? Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 yeah it is quite confusing lolon monday i was riding home and my revs rapidly dropped so i pulled over, the bike then would not start, not electric and the kickstart was lockedi got it home in my uncles van and had a look on tuesday, i took it apart abit and turned the bolt on the side to move it all manually and it all seemed to be doing what its suppost to, but the locked kick start is throwing me off the most, i didnt think it could happen loli cant see any problems in the electrics so far, but electrics aurnt my fav thing and i dont know much in that depti can give you any info you need but im totally baffled to be honest Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 basicly the bike hasnt started since monday, when i said everything seemed to be working i meant when i manually checkedsorry for the confusion Quote Link to comment Share on other sites More sharing options...
Bogof Posted October 15, 2009 Share Posted October 15, 2009 What year is your bike?IS it like this one? http://www.bikez.com/motorcycles/ajs_cr3-125_2008.php Quote Link to comment Share on other sites More sharing options...

Bogof Posted October 15, 2009 Share Posted October 15, 2009 So... does the electric start turn the engine over? If so, the engine cannot be seized. Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 no, the engine will not start at all Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 am i right in assuming that if the valves move the piston is fine??because when i turned it manually the valves moved in order nicely Quote Link to comment Share on other sites More sharing options...
Bogof Posted October 15, 2009 Share Posted October 15, 2009 Sorry, but I know the engine won't start... Will the engine turn over by using the starter... does it make whirring noises as if its going to start but just fail to start properly? Or when you press the starter button does it just go "clonk" and thats it? am i right in assuming that if the valves move the piston is fine??because when i turned it manually the valves moved in order nicely Probably. The valves would fail to open and close if the engine was seized, so chances are that your piston is OK Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 it just seems to have the 'clunk'alought for a second on monday it sounded like it was about to start a couple times Quote Link to comment Share on other sites More sharing options...
Bogof Posted October 15, 2009 Share Posted October 15, 2009 Battery is flat? Turn the headlight on and then try to start it. Has the clunk gone a lot quieter and does the light go out when you press the starter button? Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 battery is a brand new battery that i got because the one i got with it was s***, and it never electric started beforeill try it this weekend, however i dont believe it is the batterythe thing im mostly concerned about is why the kickstart wont move and why my revs decided to suddenly drop for no apparent reason while i was ridingmy tutour at collage said it could be the ignition coil but that wouldnt explain it i dont think Quote Link to comment Share on other sites More sharing options...
Guest Posted October 15, 2009 Share Posted October 15, 2009 if the piston was siezed then it wouldn't move, the con rod wouldn't move, the bottom end wouldn't move, and the cam wouldn't move so the valves would't move, its all linked... sod the kick start... for a moment..put the bike in its highest gear, sit on the bike (you'll need a helper) get helper to push you and bike (like jump starting a car) you'll need clutch in.. once moving at walking speed+++ dump the clutch, it you skid every time, you have a locked engine, if not the engine will turn, and it may catch (ignite...), see how you go and this will determine whether the kickstart gear is shagged, or the whole engine...
