TTR 110 Performance Mods

Recommended Posts

Anyone try much in the way of getting a little more power out of their TTR110 yet?? I was wondering how much the GYTR jet kit helped the performance, or whether or not it was worth messing with. If you have done any aftermarket exhaust, etc, please let me know what you thought of the performance increase.

Thanks,

C

In answer to my own question, and just so everyone else can benefit from the knowledge, here is what I have done to my TTR110 and how it helped.

1. First off, my son bent the shifter on a rock very early on, and the TTR90/110 shift levers are interchangeable. Moose makes a folding tip shift lever for about $30.

2. I dropped a tooth on the front sprocket of the bike ($10) and this made a huge improvement in lugging power. The bike is a 4-speed and still has plenty of top speed as it actually pulls itself better now in 4th gear. This was the best "mod" i did to the bike.

3. I did the GYTR jet kit, which was not as easy to install as I thought it would be. I did not see any increase in power with the jet kit, but at least I have some options for jetting now if I decide to do a pipe or go riding at extremely high altitudes as I do in Colorado on occasion (>12,000FT).

4. Dunlop Geomax tires front and rear were a large improvement over the very weak-shelled stock cheng shins.

5. I did not feel the stock exhaust was highly restrictive as I have seen smaller exhaust ports on the stock WR 250 and 450's, so I left the exhaust alone.

If anyone else found a large gain by adding exhaust and or intake mods please let me know.

Thanks,

C

Most effective performance mod, is increasing compression ratio using high compression piston, than just polish the port and rejetting the carburettor.

I am amazed at how little info is out there on this bike.Thanks for the tip on the front cog,L

I will do that along with the tires. Also ours was very hard to shift impossible for my son and even hard for me. Adjusting the clutch made a huge improvement.

C-man do you remember what your stock main was? I just bought a ttr110 last week brand new. I put a fmf power core 4, gytr air filter on it and I'm still running lean with a 95 main. I bought the jet kit as well and did put in the 15 pilot jet. Also with the new air filter does yours sound like it sucking a golf ball through a garden hose. I mean it's a loud sucking sound. Kinda scared me at first.

Ttr 110s are Yamaha's bastard child. There is very limited performance mod info and not much in the way of aftermarket parts...unless you look REALLY hard. There is plenty of info and parts available for smaller Yamaha's and larger ones, but not 110s.

I have a 2016 ttr110.  I bought the after market air filter that Yamaha sells along with the jet kit.  I took the air filter box off and took the vacuum line back and zip tied it to the frame and put a little filter on it.  I’m in MN and the bike came with a stock 92 main I think and I had to go to a 78 main cause it was spitting fuel out of the air filter.  I also put a fmf power core 4 exhaust and big bars.

I work on dirt track race cars and I used a little breather that we would use on the rear end.

I found a site called sxpatrs. They have big bore kits, performance heads and cams etc.
