KLR600 road racer

Hi all,

Ive purchased an old KLR600 engined race bike. Im converting it to electric start. I got flywheel and sprague clutch off a Klr650 from e bay. It appears that the ignition sender strip isnt firing my CDI. Can anyone advise please. Im stumped!

What is important to know here is the year of your 600 and the year of the 650 flywheel (it is not a flywheel, it is the alternator rotor).

This is important because of the differences between the 600s themselves and the 650s. There were Gen 1 versus Gen 2 rotors and there were rotors with split reluctors (the ignition sender strip).

I suspect that you have an '84 KLR600. Converting that to electric start is going to be hard, but I'm interested in your plan.

Let us know.

Hello. I dont know the age of the motor. It has housing for starter spur gears and starter motor. I suspect 1985. All of that has been fitted and is working. I think that the 650 alternator fly wheel is split ignition sending strip as you suggest. The starter clutch wont fit my earlier flywheel (3 bolt) on the 600 5 on the 650. And I cant find a 600 starter clutch.

Can I perhaps use a 650 pulse coil as a fix?

All right, then. I take it that you have an '85 or '86 KLR600 motor. These were originally set up as kick-start and electric start. As a race motor, the electric starter motor has been removed.

I would have removed the sprag clutch and the starter reduction gears as well to reduce weight.

The rotor that you have on there should accommodate a sprag clutch, as the only rotor that didn't was the '84 kLR600 rotor. That wouldn't work with your later motor, though, because the reluctor bar is in a different spot. There's also be no reason or advantage to removing the rotor and replacing it with an '84. In fact, the '84 charging system was a different phasing set-up and mixing the two, while workable, would be silly and problematic.

In theory, then, all you should need to do is remove the rotor, install the sprag clutch, install the starter reduction gears, install the starter motor, and you'd be in business. There should be no need to change the rotor and get into issues with the ignition.

What am I missing?

Could I ask that you send a picture of this bike to the e-mail address in my signature? This has nothing to do with solving your problem, but I think this would be a very interesting bike for people to see. Thanks!

This is the most incredible thing I've seen in KLRdom. It brings a huge smile to my face. This is a huge BOOYAH!

I'll ask WHY on some cheaper road bikes the factories place the Single front brake on the RH side vs the LH side. It always wierds me out.

Yes -that thing is pretty danged awesome!

You might try pinging wattman with the serial number off the engine case. He has built up a pretty good database of years vs VIN vs engine serial #.

He should be able to confirm the CC and model year. http://watt-man.com
