UPDATE: First would like to make a suggestion we need a hall of fame board, with awards like best help ending in a started rolling bike, ect..
Came up with this idea while sitting with G_Conway in-person! trying one thing after another, ripping this off putting it back on from 10am to 7;30pm. Then i had to insist that we find out some way to get his bike up the hill to my place so we can get it back on the road so he can get home. Oh ya i forgot to mention when he got to my place down the hill from it he busted his clutch cable damn that woulda spoiled my day for anything especially fixing someone elses bike.Got it up there and went inside to get us something to eat and i'll be damn if he's not pullin parts off his bike to narrow down the problem. Well anyway when ya see him on here tell him "way to look out" or shake his hand or a pat on the back i did.
Update: 1. Turns out problem was a combo of things a) faulty (intermitant) fuel pump. Have gone pumpless. b) Short in the kill switch . Able to clean up contacts fixed. Think this was main
problem all along.
So we start it up takes 1 or 2 trys bingo we have ignition, then BANG rear jugg has a back fire big time. So for the rest of the night i start soaking what we can see of the exhaust valve with pipes off useing seafoam spray hoping i dont have bent or stuck valve. Next day start up again the backfire.
So at this time am preparing to do compression check.
Questions reguarding pumpless: 1. I know i have to replace needle and seat to a 2.5 is this size correct?
2.Also have to reset the float to 4 mm
above where bowl mates to carb
(service manual states 2mm below where bowl mates to carb have read on here that serv manual is wrong). Is 4mm above mate line right?
3.I have fuel filter in vertical position, arrow on filter going the right direction. Filter sitting reguarding height in between tank and carb. Is vertical position ok?
Ok problem at hand backfire: Starting at compression test. As i understand i have to remove the decompression selinoid before test , do i have to drain my oil first? Or is this compartment oil free? And is there a gasket? Sorry dont have my repair manual with me.
And does any one know the protocal/order to hunt this backfire down?
Thank you in advance for your help
