Can someone explain the science behind having to run coils or blanks for a bike that would only be ridden on dirt? Or why can’t I just remove the lighting coils? What harm would it cause to the engine?

Thanks, Dave

Total Seal piston ring company will make you any ring you want, I had a couple sets made a couple years ago for a vintage snowmobile, that also had a wiseco pistons, very reasonable price.

Thanks, Dave

Rich, tell us more about the TIT, it improves low and midrange? Where on the stinger should it be located? Same size od/id as the stinger? How long should it be?

Thanks, Dave

Paul, don't let a few bad apples spoil your work, you've done a great job! I was in retail for 40 years, there was always a small percentage of customers we could never make happy. Keep up the great work.

Thanks, Dave

I run my Diagatron EGT/Tach on my 125, you run it off the lighting coils if you didn't know, works fine.

Dave

Doug, what oil do you use and mix ratio, what octane gas?
Thanks, Dave

Ok, what brand/part # for the 2 stage reeds, and what was the difference at WOT? Did either increase torque figures, and at what RPM?
Thanks, Dave

Thanks, that makes sense, don't the new Hodaka pistons have 2 rings?
Dave

How will the piston last longer? The Yamaha piston? And how will the engine remove heat more efficiently?
Thanks, Dave

I'm sure I got them from Paul or hodaka-parts, these are pretty high mileage, over 1000, in my almost daily rider. Found them while using a timing light to set timing, there was a spark coming from where the crack is.
Dave

Found this issue when replacing my condenser, a crack. Near the rub pad on the points, look close at end of screw driver, anybody ever seen this?
Dave

I use VHT high temp clear coat after blasting, it has to be cure with heat, old toaster oven works great. Hold up great once cured.
Dave

15/36 should be close, what mods have been done to engine, carb size etc? I'm running a 14/36 on my Super Combat cylindered 94 lower end with good results.
Dave

What do u need to have done?

Dave

Search the forum for headlight replacement, there are less expensive options

On the Klemmvintage web site there is an article about detonation, and a link to a discussion about gasoline, including AV gas. I've been running 93 octane non ethanol, with a 25 % AV gas in my Super Combat street bike 165 lbs cranking pressure, with torque grooves in head, also in my 03 KTM 200 2 s...

What is the difference in kick roller retainers if any between 100/125's

Thanks, Dave

Same thing happened to me, I drilled out the threaded and the body peices and tapped to 1/4 20 thread, center drilled a piece of threaded rod and screwed the two peices together, using locktite. Still holding, no leaks, don't over tighten.

Dave

I'm sure I read in an earlier post that Super Combat pistons had thicker piston skirts, my question is about weight. Would more performance be available from using a standard 125 piston, modifying the piston for reed valve/victory port for a decrease in piston weight?
Thanks, Dave

Would dry film coating be something to consider? Swain Tech?
Dave

What are the differences between clutch springs, such as Ace 100 to a 94 Wombat? Going through some spares and I found some large diameter springs, never seen these before.
Thanks, Dave

How about coil interchangeability, will an Ace coil work with 94 engine?
Thanks, Dave

So racerclam are you saying that you hand ground the 03 receiver to fit a 100/125 shaft? Just total out side diameter and the groove where the balls ride?

Thanks, Dave

Thanks, that's what I needed to know, sure is a different design.
Dave

Will a model 03 shift ball receiver work on other models?
Thanks, Dave
