GREENGOATCHOKER Posted June 23, 2010 Report Share Posted June 23, 2010 i had one of those (first bike after test for about a week , then 350lc) only time i thought it was quick was once dashing onto the m11 on the slip road , when wow rush of speed followed by a seized top end . the oil feeds had both popped off the carbs . nice and comfy though . and a nice one like that will surely go up in value so if the misses moans tell her it's an investment .

alext Posted June 23, 2010 Author Report Share Posted June 23, 2010 th missus is relaly fine with it - it keeps me occupied and out of her hair - and its cheaper than some pastimes I could have. I jsut have to sort the ricjness on part-throttle - any hints?? Im new to this 2-stroke lark. Link to comment Share on other sites More sharing options...
GREENGOATCHOKER Posted June 23, 2010 Report Share Posted June 23, 2010 better rich in the middle than lean at the top . have you done a plug chop on it ? to check its running rich all through most 2t's gurgle and fart befor coming on the pipe Link to comment Share on other sites More sharing options...

GREENGOATCHOKER Posted June 23, 2010 Report Share Posted June 23, 2010 two strokes run in unison with there pipes (boring stuff about resonance frequencies , back pressure to stop the charge escaping the cylinder etc) . the diameter and the length of the expansion will determin where the bike makes its power and also how much . but an aftermarket expansion like your allspeeds are desingened to push the power slightly up the rev range , it will make more but will run slightly rougher outside these revs . it could well be that your bike is well set up without listening or riding it i couldn't tell you . you can make small adjustments to the carburation by either raising or lowering the needle in the carb , larger changes by changing the jet sizes , and larger still changes by increasing the volume of your carbs . realy this is something someone in the know should help you with . you could book an hour at a dyno - they usualy charge about £25 or so pounds an hour , but some dyno's don't like mucking around with 2t's as they can go bang and end in an argument about who responsibility the damage is .

trackdaybob Posted June 23, 2010 Report Share Posted June 23, 2010 Tidy looking that. I had a red one many years ago. No mono conversion though. I likes it. Link to comment Share on other sites More sharing options...
alext Posted June 24, 2010 Author Report Share Posted June 24, 2010 well, today it point-blank refused to start until over 20 minutes of bumping it up and down the road. I dropped the needles to the middle clip and this certainly improved the part-throttle running , but it really didnt want to go first thing - just been out on it at lunchtime and it started and ran fine. One of police-bikers having to traffic-manage the Highland-show - it at least brought a smile to his bored face as I buzzed down the road past him Link to comment Share on other sites More sharing options...
alext Posted July 13, 2010 Author Report Share Posted July 13, 2010 further update;- after completely refusing to start after 2 hours of bumping... I re-stripped the carbs, blew through everywhere with the airline, and now it stsarts perfectly on choke!!!! but now once I get off the pilot-jet the left hsnd cylinder shuts down - think Ive got dirt somewhere else now - think I need to get these carbs cleaned properly!!
