Well, some of you may have followed that I don't like riding my 124+r bike because it has no off the line grunt and you cannot lug it around at 3000-4000rpm. I even put the original size flywheel back on and still no dice.

How about putting on a TB manual clutch with the billet housing and taking off the Takegawa Special Clutch? Anyone think that it would be an issue? These +r motors, despite what people report, only make 13-14hp without any major manipulation...so I figure that's about what I have...other than an s25 cam and some mild portwork.

I'll save the takegawa clutch cover for my xtreme-to-nice project which will be an interesting concept for sure.

What transmission will you be using in the 124 +R?

fatcaaat

The motor is already built. It is running a 2003 Honda monkey 4-speed tranny.

Switch to a smaller carb and intake for better bottom end

also lower your gearing

fatcaaat

The smaller carb and intake may work but on my TB108 I run the same carb and have no issues....its the crank inertia that makes it spin too quickly for me.

On gearing...if I went lower than 17/32 it would make too many RPMs on the street since the cruising target for this bike is 50-55mph all day for 30+ miles at a clip.

I think it is just the inertia I don't like...I've had non-knifed cranks with the same clutch and haven't had an issue.

Up the compression, longer intake manifold, advance cam and ignition timing?

Not sure more flywheel will offset big cam and ports?

I will try advancing the ignition timing. I have the LONG kitaco intake manifold, so not there and I'm not spending money on a cam...I don't think they make advance cam gears for 2-bolt cam applications do they?

firepower354

I think Tak has the cam sprockets, but I haven't seen them besides in the old catalog. We slotted my GS1100 ones all the time, so the 50 types should work the same.

would it not be possible to put on an oil slinger that would slow down the crank quite a bit

Adam z50+R

the cam sprocket on my dohc is elongated to adjust cam timing as you mention, firepower

the take' s12 camshaft improves the pickup of the +R's dramatically (more cash tho)

billy/ i doubt a slinger would fit under the clutch cover being it a slim take' one

a crank mounted clutch may be the answer,

but if your too used to the big strokers fatcaaat, (your 177)
its doubtful you'll get the tak to mimick it,
as its only half the torque output

ps. get the welder out and put some weight back on the tak crank LOL

fatcaaat

The kit came stock with a s12 camshaft and I sold that off to purchase the s25. I didn't realize there would be such a difference...however the top HP numbers are 2hp different on the top end...not that I'd run it there too often. I think I made a mistake selling that cam.

I'm going to try to advance the timing a bit and see if that helps out. Maybe I should just take the bungled pitster pro overly advanced flywheel and swap it in and see what happens?

Are you running a VM26? If so, switch it to a PE28 or PWK28. The difference is astounding. The PE is a lot easier to tune than the VM, and your bike overall will make more power and run better with one installed.

fatcaaat

I heard this before. I actually used to have a TM28 Flatslide on it and I always had some trouble with the idle. The VM26 is perfectly dialed in and idles fantastic. Now I am sure that a 28 will produce some larger numbers, especially on the top end, but the majority of the riding will take place 6000-7000 rpm I would think and having a huge carb isn't likely to help that much in that range.

To cut right to the chase, it doesn't have the torque or the flywheel affect that I want, which isn't going to change no matter what carb or how advanced I make the timing.

Here is my point. I just assembled a Honda Trail Bikes 108cc kit with race head and stuck it in another CT70. It has the TB manual clutch on it and a Lifan mini outer rotor on it. This bike, while having much less power, is more along the lines of how I want the bike to perform for takeoff...flywheel affect, I can lug it down at 3000 rpm in 4th gear and it is fine.

I rode this Taky 124+r, the TB108, and a YX170V2 all back to back yesterday and by far the 170v2 is the easiest one to ride and has WAAAAAAY more torque. It has a LOT more power than the 124+r as well.

I think maybe just some flywheel affect is all I want, but that means I have to give up my fancy clutch (and not sure a TB manual will hold 14hp) and then I also have to drill/tap the cover so I can keep my oil takeoffs where they are at.

What type of ignition has the tak? Maybe a ND ignition with full flywheel can help(as in not lightened).

fatcaaat

The taky has a complete, non-lightened xr50 flywheel on it.

50r

its all in the cam brother,you sold your bottom end $ maker S12.
S25 is more top end.theres a big noticeable difference between them
