'12 TXC310 Build Up

[Connor]

Hey Connor, bike looks great. I just put my ZTR supplied FMF exhaust on last nite(thanks Tinken) & I have to agree 125%, the sound is amazing. It makes you want to stand there just blipping the throttle. The Harley guy across the street even came over to see what was making the noise. So what exhaust guard do ya have there? I'm gonna need one. Time to get that thing dirty....

The one pictured is a Husqvarna part. I ordered this guard out of there hard parts catalog. It fits pretty well on most exhaust. The only exhaust that it didn't fit with was the Rocket Exhaust. The link to the catalog is below. It is not cheap though, its over $100. I forgot to add that in my parts list (ordered it when I bought the starter motor).

Ha, I thought it looked familiar. I'll probably get the FMF one. Still need to verify if I need the starter parts...

Well I rode with mine today on the motocross track and the woods track. It is pretty impressive the gain in useable horse power this pipe brings to the table. It is stronger every where, from bottom to top. It also sounds awesome! I had at least 4 people comment how good it sounded and that they've never heard anything like it. The bike now pulls much harder and sounds plain mean! As a side note I will say that I do not run the quiet insert. If I were someone that just rides tight single track or trails all the time I wouldn't buy this exhaust, because for simple trail riding the stock exhaust is just fine. However, if your in my position and you ride some motocross track and some fast trails as well as some singe track than I'd recommend the exhaust.

Hey Connor, the good news is that Moose has some woods bars that don't need cut down. They're already cut down to 30" with full room for controls. I went with the Burleson bend, swept back a little, but they also have several others to choose from.
http://www.mooseracing.com/products/?productId=114628&productGroupId=1221 I didn't like the way my Cycras fit on the stock bars but they're prefect on the Moose Flex bars. May be some other brands out there I don't know about. I'll get some pics up mayb tomorrow.

Awesome, good to hear! The quiet insert will actually increase your lower torque and is much nicer on the open trails, but the open pipe gives top end rpm power, great for the mx track.

I'm sorry I may not have been clear. I like my bars, I just need a new way to mount my handguards. I know BRP makes a different mounting system but their site says it won't fit husqvarna's.

I will have to try it with the quiet insert as well.

Don't be afraid to cut and bend your handguards until they fit....you may have to drill new mounting holes in the front of the guards.

I had already drilled new holes to make them fit on the stock Husky bars. Tonight I made some adjustments to the front break mount and just moved it around a little and got them to fit. All is well now. Now I just need to ride again.

Hey Tinken what do you guys recommend to do to the EFI system once you add the exhaust? I have the JD tuner and was wandering if I could get a little more out of the bike by playing with the EFI controller to make full use of the new exhaust. People at JD said to go richer since the new exhaust would have more air flow, so in turn needed more fuel to make the correct air to fuel mixture. And the '12's have always been a little finicky on the bottom end, so I decided to change some settings on the low end to see what it would do. I started out with the low end set on 4 (the stock setting that JD sends it with). I really didn't have to many complaints on this setting. Did one lap and came back in and turned up the fuel to level 5. Ran another lap. Results? It was worse. It popped and sputtered at low end a lot more than it used to. So I came back in and changed it to 3.5. Went back out and it helped, but I couldn't notice much of a difference from the beginning when I started with 4. Than I let some friends ride it on the mx track and they said it had a hesitation on the low end on the mx track. So in the end I stayed with setting 4. However, Im surprised it got so much worse when I made it richer, considering everyone thought it would help. Either way, next time I will do some top end testing. I think this bike goes kind of flat on top (that's the nature of a bored out 250 four stroke), so I am going to see what the the fuel tuner can do for that. This also has an accelerator pump setting on it, but I'm not sure exactly what that effects. They told me that most woods riders turn it down as far as it can go, I am guessing to keep the power smooth all the time. But I am going to try and adjust it as well. Btw I added a link to a video that I thought was pretty cool. Check it out if you'd like.

Anyone can comment on the EFI tunning of the 310, I have just been wandering what ZTR found out about the 310's. And no, adding a PCV is not an option. I used one on my ltr450 when I had it, and liked it. But the biggest problem was that I didn't have the auto tune kit, and therefore had to take it to a dyno everytime I wanted to change the mapping because I couldn't understand that confusing chart lol

 

[Tinken]

The JD tuner is really just a toy. It's fun to play with and helps here and there, but the pro's use powercommanders on your motorcycle model. Ty used the power commander and the auto tuner when he raced the MY12 TE310s. It's not cheap, it's an investment. But it will give you the best a/f mixture you can possibly have.

 

[LandofMotards]

With the way the auto tune works I imagine you can download a map from zip-Ty and it would be close enough

 

[street2dirt]

Another ? Mr. Tinken. I'm still trying to wrap my old feable mind around this whole PCV vs JD vs ?? I know the PCV + Auto tune is golden, but would the the PCV by itself give big gains if you can add auto-tune later? Or just hold off until you can invest in both?

 

[LandofMotards]

I don't even know if auto tune would matter to you. Do you change altitudes? Sorry if that sounds wrong but the last time I was at Disney World (in fifth grade) it seemed pretty flat lol. PCV with a generic map may work and best with a Dyno tuning.

 

[Tinken]

You can use the PCV with a dyno tuned map and add the autotune later. Just depends if the generic map runs the bike effectively or not. You can take your bike to a dyno and have it tuned with the PCV, which will work fine, but it costs nearly as much as the autotune.

 

[Mike-AK]

Great...something else I didn't need but can't live without...

 

[street2dirt]

No, not much alt change here LoM. One HS a guy used his gps heart rate monitor device & the total altitude change was 7ft. A big hill at the Gatorback round would have been maybe 75. May try the PCV, with a Zip-Ty map of course.

 

[Connor]

Alright well ask Ty this. He should be able to see the original map and the new map that the auto tune kit made, he should be able to see them both on the same graph on the dyno, and in general what did the auto tune do? Did it make the bike richer or leaner and where. There should be an air to fuel ratio that he can see. I could see it when I had my PCV on my race quad.

After some riding time I'm learning more about this bike. The power now hits much harder and the bike is over all faster. The suspension is going to need some work though. The front and rear are not balanced (for my 150lbs frame). The front is softer than the rear. No matter what I ride the bike is unbalanced. In the woods the forks feel comfortable and the shock feels rough, and just not tuned correctly for the woods. On the mx track the front end will blow right threw the stroke but the rear end takes the jumps well. I have not yet touched a clicker setting since I've got it. All I did was set the sag to 108mm, and it seemed to help. Now that my power and ergonimcs on this bike are all where I think they should be, I will start looking to make the suspension better. Im going to see if I can't just do some adjustment with the clickers to get me where I want to be, or if I need to revalve the bike. More to come.
