    Got some riding time on the bike yesterday! Super nice out. My little sister (we are both in our 50’s haha) has a license, but she hadn’t been on a bike in 2 years so she rode the TTR and I rode the KLX and we putted around for about 2 hours. She’s timid but had a good time getting used to riding again. I really enjoyed just going low and slow and looking at the beautiful scenery. That’s another good thing about the KLX. It’s such an easy bike to ride at any speed.

    Cool project. Reminds me of the days when they put Volkswagen Beetle pistons in Moto Guzzis's.

    Rear shock is done. Picking it up on Monday from Cogent. Great guys to work with! Can’t wait to get it back together. Thinking with the suspension upgrade it’s now time to complete the big bore kit!!

    I'm enjoying this project. Looking forward to the details if you're willing to share.

    Thank you,
    Yesterday I made a head gasket in solid works, still needs some tweaking.
    The piston was delivered and needs some minor machining I think.

    So I milled down the piston, still have to mill the valves in it.
    I am in doubt whether I am going to hone myself or by a local machinist.

    Every now and then I stumble around a mention that someone put the Acerbic 3.7 gallon tank on a 09 + on their bike with some mods, instead of the 3 gallon tank, but I can't find anything info explaining what has to be done to make it fit. Do you mod the tank or the bike and can you still get to the choke with the bigger tank? For the time being I ordered a knock off 3l rotopack to strap on the luggage rack. One down side of the big bore kit is less MPG but a worthy trade off so far.

    Thomas Edward did a custom 09+ with this tank.

    You should wait for the judgement of the big bore on mpg. When I went from 651cc to 678cc along with a reverse cone megaphone exhaust on my KLX650 I went from the original 50 mpg to 60 mpg. Seems I got within a mile or two of 60 mpg no matter how I rode, all highway at higher rpm or dual sporting on dirt/gravel roads. Clearly the bigger set up was more efficient, plus I could use the additional grunt of the bigger engine to short shift.

    The thing most riders find with the big bores is they can pull stronger at low rpm (stock cams) so they can either pull a taller sprocket set up or run higher gears in given situations. You might just hold the ground with the big bore.

    That's a cool build. Interesting about the new sub frame. I just wonder what the slight mods you have to do to get the tank it to fit on a carb bike.

    I cannot image it to be that much of a hard job.

    You need to do some searching in the forum
    I know people have used this fuel tank and posted results. I believe the choke knob had to be modified to make it fit

    I got right at 50mpg on my 09 with 351 BB kit on Saturday. Most of the riding was in 3rd and 4th gears on fireroads at 35-45 mph.
    Stock carb, FMF pipe and muffler.

    Thank you all for the recommendation to Cogent! They are top notch for sure. 5/5 would use again and tell everyone about them. Bike is all buttoned back up and ready to party!

    I just got back from a 1,400 mile ride around the Upper Peninsula of Michigan. Found some really nice colors and some amazing trails and dirt roads. I've been exploring the UP for the past 10 years and it never fails to impress with the variety of riding. Now I got to work on a ride report. And yes I know I have a lot on the bike!

    Sounds and looks like a great trip. How did you do it without a $20000 giant bike?
