OK Carb gurus...
My 98 ACE 750 was backfiring only on decel... I turned my mixture screws out 3.5 and it got much better but was still there... I took it to my friend to have him install a dyno jet kit (as he said was best for these carbs).. Well I picked it up today and ITS WORSE! It runs greatbut pops and crackles BAD on decel. I did notice they adjusted the mix back in to 2.5 but still! there should be some improvement right?
I am thinking they didnt drill out the slides maybe? Think im safe going back out to 3.5 w/ the jet kit as well?
I am sooo pissed right now. I love my GS soo much more as I am used to working on it and just did this stuff myself.
Any input would be awesome!
:cheers:
Is this really an issue, my Z750 pops and crackles on deceleration, I've just put it down to the pipe, it's got a 4 into 1 and basically a race pipe.
Yea, its pretty much a straight pipe so I know its gonna pop a bit but I cant afford new pipes and I just dont like it when cruising slow in a residential... Its a bit too loud
Just knock it up a gear and labour the bike around the areas.
It's mainly a couple of blocks around home that I baby the bike to keep the noise down, the rest of the time it's give it all it's got, especially in underground carparks.
Even in 5th it poped loud! :cookoo:
I turned the mix out to 3.75 :icon_eek: (2.5 factory) Just about the edge I guess... But it sounds MUCH better now. It will have to do until I find out what sice jets I should run.
For now I guess im ready to rock at the local 250K+ motorcyle rally here in town this week!
By the way...
Welcome back bud! Its good to hear from you :cheers:
Thanks.
Once the novelty of the new bike wears off I'm going to go back to riding the GS to work, it's a lot quieter, plus it's got heated grips.
