THIS IS WHERE WE LEFT OFF AT THE TXT300 THREAD...

 

This is probably a newbie oriented post that might irk the purists, but I've made some progress on my Txt300 mountain goat.  I've got it geared down and added a flywheel weight and slow throttle so I can plonk along trails at a walking pace. And I'm experimenting with mounting a seat.  It's working pretty well so far, and is comfy and solid. But it needs some final finishing cosmetic touches and proper support for the mid section.

Hey there Scottro! How ya been? I'm doing much better. Gaining strength back and just found out I'm cancer free. I will never talk again but I'm alive to ride my Gasser! I like that seat. Did you fabricate that? Looks good and I can imagine it's comfortable. I bought a Jitsie seat for mine. I also have the slow throttle. Can you please share with me what sprockets you installed and also what chain? Did you have to change the chain guide? And please can you give me a part number for the flywheel weight? Id appreciate it so much. Message me if you prefer. I bought an S3 low compression head and insert but haven't installed it yet. Bob suggested not installing it until I see that I can continue to start it. I missed the forum. I just wasn't feeling well for awhile. I dropped down to 113 pounds and really thought my riding days were behind me there for awhile. But I gained some weight. I'm 123 now and lifting weights religiously. I can start the bike now but only using the technique we discussed. And standing up on the bike with it leaning against something. That's the only way. Feels good to be back. I keep in touch with Bob. He's happy I start the bike now. I was reading some back posts that I missed and your right about the octane in European countries. Their 98 is our 92 I think I read. I'm running Sheetz or Rutters non ethanol 90 octane 70:1 with Motorex oil. It's a tad rich and I might take it to 80:1 after putting more time on the motor. My bike hasn't been run for a quite a while because of the weather. I didn't drain the tank or carburetor. Being that it's non ethanol gas do you think it will be okay until better weather? I had a heck of a time with a quad that sat with E10 gas for a few years and it was a nightmare. Had to replace the fuel pump, tear the whole machine apart just to get to the carb. Total nightmare and I don't want to go through that with my bike. I hope the non ethanol gas won't cause problems from sitting. Captain Bob rode my bike back before Christmas and he came the whole way up here to see me. Great guy! Really nice people him and his wife. He's planning to come up here to ride this season and could you be able to go too? That would be cool. Really good friend. He said my bike runs great. He liked it a lot and must have started it 15 times that day no problem. Talk later buddy

Hey Butch!  Glad to hear you're up and about and getting the bike started.  We should probably start a newbie thread in some general forum area and not clutter this thread with our chatter.  Yes. You, me and Bob should try for a meetup and ride this summer.  I'll pm you the parts list.

Glad to hear you guys are up and about.  I have been practicing static balancing and although, I certainly am no expert, I am beginning to get the hang of it.  Scottro, what did you end up with for final gearing?  Butch, I am really glad to hear you are still able to start the beast.  That is awesome.  Yes, we do need to do a ride this summer, I am definitely up for it.

Hey folks.   

This is the rear sprocket I got.  https://trialssuperstore.com/products/rear-sprocket-jitsie-soild  I got the 48 tooth.   Up front, I think I went from 11 to 9 teeth.

This is the chain.  I took out 4-6 links.  JT Chain JTC520X1R120DL (520 Series) Black Steel 120 Link Heavy Duty X-Ring Chain with Connecting Link https://a.co/d/8gDJF4a

The stock chain tensioner flexed far enough to work fine, but I bought an extra slider to contact the chain.

This is the flywheel weight I bought.  https://trialssuperstore.com/products/gasgas-pro-s3-flywheel-weight-idria1

A couple caveats with the flywheel weight: It comes with a spacer to give an extra 3/8" or so inside the case cover.  I had to modify the spacer with a Dremel to fit over a raised "nub" .   Also had to move the shift lever farther out on the shaft to clear the case cover.   I had to remove the bash plate to access the shift lever Allen bolt.

Butch-- Leaving gas in the machine during storage:   I've also had bad things happen to bikes and equipment.  I try to empty the tank and run the carb dry.  I can't always do that though. In those instances, I shut the petcock off, start the bike and ride or run it out of gas. Then I open the fuel drain on the carb and let whatever's left drip out. Then, I close the drain.  I also use EZero in bikes and $$$ canned fuel in most lawn equipment and chainsaws. It helps.  That said, I'm a near expert-level cleaner of gunked carbs, because there's always something I forget.

I was playing around in the garage and thought I'd try fitting a DOT legal headlight to the TXT300.  Looks pretty good.  If I decide to use something like this, I'll power it with a Milwaukee 18V battery and leave the bikes electrical system out of the equation.
