Today I took the stock shifting arms and linkage off. Found a blue billet Honda or honda clone shifter. Ground it down to fit under the cases, had to make a screw also and drill out the M6 threads and run a bolt thru w/ lock washers and locknut. Now everything is backwards 1st is up, and 2, 3, & 4th are down. Still the lousy rough shifting as before, but it looks better and is much lighter.

Nice might I ad to loose the fold feature on the end because I had such a problem with mine every time I tried to go for a quick upwards shift it would fold so I bolted my folding leaver
What I love about my 18 is my shift pattern with the linkage was all down with neutral all the way up now without it its all up like normal I'd hate to lose that motor its the only one I've seen with a all up/down pattern

i tried that same setup, i couldnt stand down for up shifts...LOL i learned to ride a dirt bike with a 5 speed standard honda 1 down4 up trans back when i was 8, so it just feels akward...

It sucks going into a left and having to dig your foot under the shifter you would either have to downshift before the corner or not lean in as hard I'm trying to adapt my 18 linkage to my x15 right now for that reason

Exactly.... and i was worried about how low it needed to be comfortable to get on top of the shifter to go up.... I had the shifter that way for all of 15 min....

If I was racing on a track, this setup would not work, I would have to pick up the the lever to down shift. I can see alot of missed down shifts and sliding off the track in the middle off the corners,lol.
I run a 3 1/2 mile run, in the redwood forest, on a Highway with a 35 to 45 MPH speed limit, there's logging trucks and stuff flying down the road too, so, I am just Road Kill,lol. It's all upshifting and flat out, maybe one down shift into third, then back to wide open. It has a PBU 28 tooth billet alum rear gear, and I started w/ a 16 up front and hit 55 in third on the China speedo, but it made 4th to high geared. Since, I put a 15 up front, but have not tested it yet. Have a 22mm w/ the pilot and main jet gauge drilled to the next size. The PZ19 on it now, has both jets one size bigger. Yesterday the rubber mount broke off the blue finned CDI, and it was hanging down, so got out my 200 mph tape and put it back together. Has a hp coil & X12 hp side exhaust that's Very Loud.
It was running real hot at the end of the run, so I added a $60 oil cooler, and mounted it to the upper left under the frame, it keeps it from blocking air to the engine. That helped alot, runs cooler now.

I modded/custom built my shifter and it folded the right way and worked finer than fine............All my superbike controls were customized for my feet and hands.......

EPR...It sounds like you need to mod the clutch throwout/adjustment assembly/actuator rod of all sharp edges and burrs then readjust the clutch...........

Yeah, I need to do both the X18 & dirt bike 110cc 4 speeds, they both are ruff shifting. I just ordered a blue heel-toe shifter to day and will try that out. Put a foot shifter I had laying around on my 125cc ATV w/ forward & reverse. Going to post photos.

pop off the clutch side cover(not the one to adjust, the actual engine side) and see if your cam for the shift detent is tight...that made a world of difference on mine... screw was almost ready to fall out....only thing holding it in yet was the primary gear.....

Thanks, will have to look at that, adjusted the cable cam on the right. So, that would be the left side case cover, where the clutch assembly is. Never had the outer covers off on any off mine. I rebuilt my 750cc to 836cc 4 cyld Honda motorcycle before. I got a Clymers book on Hondas Single Cylinder 50 to 110cc 1966 to 1999, with photos, $28 covers the whole engine and everything else.

the detent cam is right side too...you have the clutch right off the crankshatf, then that has a gear on it to the primary gear. tucked right above that gear and mostly behind it is the detent cam. you will need to drain the oil to do this since these engines are a wet clutch system.

in this pic (not mine, stole it from the intarwebz) the far right shaft with the small gear is whats behind the clutch, the other big shaft will have the primary gear, and that star shaped wheel in the upper left is what you want to check...make sure its all tight... if you are good with a small pliers or needle nose vice grips you can do it without pulling the clutch or primary, which you need special tools for.

Great photo, so it looks like the shifter shaft comes all the way thru the engine to operate the shifting star. I got it, looks like that screw has been tightened a few times. I just ordered a heel/toe shifter yesterday to see if it works better.
On eBay I just got a racing coil for $10 and red alum oil cooler for $19 and $19 S/H, less than $48 to my door from China. jrmotorpartsdepot on eBay, has all kinds of 50cc thru 138cc Honda clone stuff cheap.

It's just Junk, I have owned many Hondas from 50cc to 1100cc they all shifted great.
