wings36,

Download this service manual, it's for a Talon Buggy. The manual has all the info you need to service the gy6. The pdf file is about 21 megs so give it time to download if you have a slow connection.

Good Luck,

Update -

The problem is in the shifter linkage. I have it adjusted correctly now and the stutter is gone. I'm still gonna have to get a new linkage bolt; the one that's on there has some stripped out threads on it. There are 2 nuts, one to tighten the right side of the bolt and one to tighten the left. The one on the left was sloppin' around in missing threads. I moved the nut farther to the left to miss the stripped area and then readjusted. (Hope this makes sense) Anyway I think the missing threads possibly caused this. I'll have to give John a call on Monday.

That was a lot of trouble for how easy of a fix it was.[img]i/expressions/face-icon-small-tongue.gif[/img] But I did get some new jets out of it![img]i/expressions/face-icon-small-smile.gif[/img]

Thanks for your help everyone!

Note: If anyone gets the impression that Jetmotos are just another chinese POS, I'd have to disagree. All in all I think this is a great bike so far. The things that have been wrong with it are minor, and John at Raceway has been very helpful at getting me what I need to get it tip top. So far for the price, I am very happy. (I'm also learning a lot[img]i/expressions/face-icon-small-wink.gif[/img])

 

here's a link on jetting information, some of you need to read it and learn how the carburetor works and how to rejet and how air denisty plays a big part in jetting

Thanks for the manual smb05. That'll come in handy!

As I was reading, I knew exactly what the problem was! I had my 2 new 150s out on 50 mile trail rides this past weekend, and BOTH of them did this! I started by adjusting the dogbone in the transmission linkage shorter (loosening the two nuts and turning the link bolt to clockwise). This worked for 10 miles, and then 1 of the machines started hesitating again. I already had the dogbone as short as it would go, so I had to kick the linkage arm on the transmission spline back a couple teeth (clockwise viewed from top of machine). Now both are good.

All 4 machines (2 150s and 2 250s) all need a serious chain tension adjustment after 150 miles this weekend. Really, still being broken in. Jim at KidATVs (Minnesota) has been helpful when issues come up.

 

All -

One other interesting tidbit (for those of you who are not ATV maintenance experts). On Saturday, one of my 250s suddenly died. We did a pull start, and it was like there was a super weak spark - it would run a bit for a couple seconds and then die. During a pull start, I started flipping the left on/off thumb switch and the engine popped right off.

I took the switch apart, and found quite a bit of moisture (rain, I guess) in the switch contacts. I wicked the moisture with a paper towel and put it back together. This resolved the issue.

My family had an absolute blast on our JetMotos this weekend. No doubt that we've had quite a few issues (one each ride it seems). I explained to my kids that I didn't have the $$$ to pop for 5 machines unless we started with JetMotos. We all get frustrated at times, but we are also building a knowledge of the machines that me and my kids will hopefully someday appreciate. I hope this helps you other JetMoto riders.

peace--

 

tpetry, cool to see someone else bought two of each as I did. so far are you happy with them? Even though they have had a few problems here and there we still have enjoyed them and have had them out around 20 times this summer! It's been fun to see my boys learning to ride and out on quads having fun!

 

outofline -

I'm pretty happy so far - although I did expect them to be a bit less needy so soon. We went riding with friends who all have workhorse Grizzly / Honda / etc. We traded machines periodically (one guy had my Honda 200 atc out) Everyone seemed to enjoy the jetMotos the best - I love my 250 sport.

We went riding on a state forest (Akeley, MN) where tons of logging had occurred, and were climbing uphill over downed logs/branches as big as 10" diameter. I don't think my machine will last 20 years if I keep that up, but it performed really well (I kept up with the Grizzly 600).

My 12 year old has no interest in the maintenance/fixing aspect, but my 14 year old is all over it, so we're learning together. That was a big part of the purchase.

Is the chain adjustment on the 150 the same as the 250? Also, I think my 250s are as tight as the chain can go, but its still very loose. Is there an option of pulling a link? Thanks!

 

Which front sprocket are you running, I changed to a 14 tooth on my 250's and am much more pleased with the climbing ability! Is your grease zerk hitting the metal from the swing arm? If not you should be able to adjust that chain real tight! The 150's do adjust very similar but you use a hammer to tap the tab on the housing down wards.

Now - not too tight! I got a new chain for the 150 as the original had several really stuck links. I'm not sure how I over tightened the chain as it seemed to have a bit of slack. The chain broke a half hour later. When I tried to put it back on, it was way too tight. I also discovered the position of the swing arm makes the chain looser or tighter. Just make sure you check the chain tightness over the full range of motion of the swing arm.
