98 srad 600 runs fine as long as i baby it. but if i get on it hard it backfires dies and comes back on a few seconds later. nothin seems to solve the problem i had the valves adjusted cause it was time for it, completly rebuit the carbs and changed the spark plugs. cant find anything else wrong with it. need some ideas please.

you're gonna have to be more specific with your problem (what rpm's does this happen etc.)

 

[thatsme_25113]

it happens at 9000 rpm or higher and only 2nd gear and up rarely in first. cant go over 95-100 cause it backfires if i try to speed up at all at that speed

The first thing I'd do is change the plugs again. It's possible that you could have gotten a bad one and it isn't firing properly. Did you follow the manual when you rebuilt the carbs?

sounds like my bike, where you get it from LOL

lol tangy he stole your bike!!! just playn... I would try another set of carbs. Borrow a set from a friend with a srad. It may not be the problem but its one less cause..

the carbs on it are a diffrent set i have 2, rebuilt the spare and put them on. problem stayed will the diffrent carbs. will try diffrent plugs. a friend said maybe the bike was runnin lean and to move the clip on the needle or put a spacer on it could that help?

If it happens with both carbs then it is probably a fuel delivery problem. Check your fuel pump.
