Backfire in air box?!

Post by Benno_0214 »

Hi everyone!

I have recently bought myself a storm, I'm loving it! Just a quick question really, is it common for the bike to pop and backfire into the air box? Mine seems to do it every once in a while at very low revs, and sometimes cuts out :?
A guy I work with had a storm years ago when they first came out, he seems to remember his did the same?
It's a totally standard bike, runs really well apart from this occasional air box fart!

Any help would be apprieciated!
Cheers Ben

Greetings

'carb fart' perfectly normal - just raise the idle a notch to lessen the chance of it stalling in a tight corner.

Post some pics of your bean eatin' storm beasty.

If you get the carbs sync mate it helps a lot and doesn't do it quite as often.

If you going to be doing you CCT's then it's the perfect opportunity to fit a front cylinder vaccum take off for carb syncing http://www.vtr1000.org/phpBB3/viewtopic ... 31&t=18430 and do a carb sync. :thumbup:

Having the carbs set a tad rich helps to stop it to

You seem to like posting links :lol: It's good that your reading all these threads but if you read that thread all the way through you would realise that that came down to a carb balance as well. Yes TPS does help but it could just as well be a simple carb balance that will sort it out.

IMHO I think it generally comes down to the bike needed a good tune up. This could mean altering a few things. Remove carbs and give them a clean, check the jetting and mixture setting, while carbs are off adjust the TPS, also while carbs are off fit a front vacuum take off for carb balance simplicity. Re-fit carbs and balance them. Warm bike up to running temp and get the mixture spot on, then maybe another carb balnce.

Or just turn the idle speed up a tad and forget about it. :lol:

The worse it is the more attention the carbs need as Carl said
