Dynojet. Just not right!!!

Hi All,

Put a post on here a while ago asking which dynojet kit to go for on my RRX with a full Akro Titanium exhaust cause of the lumpyness.
After lots of excellent advice i decided to go for a stage 1 kit with a K&N filter.
Had the carbs balanced and fitted the jet kit myself to the manufacturers specifications.
Set the needles to the 3rd notch down and set the a/f mixture up at 2.5 turns out. The bike didnt want to pull away without cutting out so i moved the needles up to the 4th notch down and it felt better but still had alot of flat spots low down. I then moved the needles down another notch to richen the lower end more but it hessitates all over the place now especially pulling off and seems to launch itself in first gear.
Before booking some dynotime i was wondering if anyone could help with any advice on the situation.
Thanks in advance.

Re: Dynojet. Just not right!!!

Here in the states we classify our bikes by year, not by RRX,Y,Z. Etc. so because I'm a little slow, what year is your bike? And then explain the year/letter designation so I don't have to feel so uninformed.

Re: Dynojet. Just not right!!!

RRX is a 1999.

If the bike isn't braking properly, you don't start by rebuilding the engine.

Yep. Alphabet starts over again at 2010 so A is 2010, B is 2011 etc.

Re: Dynojet. Just not right!!!

Not quite Ian...
Fireblades are updated every 2 years with each interim year having a colour scheme change.
A RRX is a 1999 but it is the same model as the 1998 which is a RRW. Although, the colours are different.
Anyways, back to the question at hand. Any ideas??

Re: Dynojet. Just not right!!!

I'm not familiar enough with Dynonet's kit, however am very knowledgable on the Factory Pro kits, and I only speak of what I knew back 20 years ago. I had a dynojet kit in my old 600f hurricane. I learned after that Dynojet made their own jet designations, not corresponding to standard Keihin numbering. The factory kits provided genuine Keihin jets, and you could then buy extra jets from Honda if you continued to modify your bike ( as I did with my 93 to 1024cc, using stock carbs). Anyhow, what designation did the mains come with in your Dynojet kit? And did it have you replace your slow jets as well? If you have richened the needle's to full rich and it made the problem worse or no better, try bigger slow jets, then bring the needle back down. If the kit came with multiple main jet selections, try the next bigger main jet and bring the needle back down to recommended height. It sounds like a stumble that can be worked out, it's just gonna take some fiddling. It's tough without a dyno chart to know wether your rich or lean in a specific RPM range. PS thanks for the clarification on the lettering. I knew it corresponded somehow, but always like to be in the know as far as the lingo goes. No harm no foul.

Re: Dynojet. Just not right!!!

So what size primarys and mains are you running? How do your plugs look? Black or real tan white? Does it burn real hot out muffler or smell like unburnt fuel.

Id like to help but you need more descriptive of whats going on. How it smells plug condition etc.

Rubber side down, One wheel to the sky for those who we won't forget. R.I.P homies miss you.
