XR600 Electric Start?

35 posts in this topic

Does anyone know if or when Honda added an electric start to the XR600? If not, does it have a manual or automatic compression release? Thanks!

I had asked a similar question awhile back without response. The XR-R did not come with an electric start but does have a manual decompression lever. I believe there are some aftermarket companies that sell an e-start for the XR, but it may be limited only to the 650's. Not sure if you can add an L model e-start to the R model though, has anyone tried this, and if so, how difficult?

I have asked this question before and never gotten a good solid response. But, I did see where a guy took an XR600R and put all the e start stuff, cases and all oon it....can;t find it (the thread) though!

That was me adding electric start to a 2000 model XR600R with the 628cc HRC motor. Didnt want to mess with my beaut motor - only has 1800km on it but wanted e-start badly.

No one makes a kit for estarting the 600R. I would be persuaded to start packaging the basics if enough people show interest. The probably won't though.

It can be done is the simple answer and you need a good mech and good Honda oem parts supply. Most of the bits bolt right in.

I am 3/4s way through having it all complete and back in the bike.

Briefly I have done the following:

Bought XR 650L side case, wiring loom, starter clutch & gears, starter button, clutch arm, all starter motor bits. All of those bits bolt right in.

Bought oem 450X battery.

Bought XL600RMG crankshaft. (this is what makes it work)

Have had modified the following - XR600R stator rewound to 250+watts, married the 650L wiring loom to the 600R wiring loom, married the starter clutch to the XR600R flywheel - both of which have been weight reduced significantly.

The parts all fit - the side case was made for the XR600 - it bolts straight in, the XR600 even has the blanks on the engine case to mount the starter motor.

You cannot adopt the 650L flwyheel (nor would you want to) as the 650L has an entirely diff electrical system and runs lower starting voltage.

Right this minute the engine is complete - with starter motor mounted and all bits go straight in.

This is a long term project - one though that has produced possibly the worlds first genuine XR600R (nee HRC 628) with electric starter. It will be completed in about a month or so - photos will be posted and a list could be done of all the bits necessary to do it if enough people show interest.

Most other conversions are just 650L motors in the 600R frame. Those who know 600s and 650s know the 650 has major mechanical differences to the 600R.

The 450X battery is simply awesome - genuine yuasa super high CCAs. It is being positioned next to the carb.

Other mods which are also getting done at the moment are:

Fitment of entire 2005 CRF450R front end - forks, brakes etc. Braking wave disk too with black excels either end.

Fitment of 2004 CRF450R FCR-MX carb - much lighter throttle pull and power response.

This is all in addition to IMS tank, setrab cooler (xrp lines), high wattage lights

Hey there,

Glad to hear things are coming along with your project. Sounds awesome. I can't wait to see pics.

seems like allot of work and money for the e-start system which is probably why no one except rmhrc630 has tried it. if you can post the details, cost, photos on how to do this modification I sure would appreciate it.

coming soon, coming soon!!!!

just got word - motor is all back together and the thing works!!!!

all the auto decomp works perfect!!!

the 650L starter turns the high compression HRC engine over perfectly!!!!

anyone know of any US guys who have converted the XR600R? I'd like to hear from them.

how much are people prepared to pay for genuine e-start on their XR600/XR628?

Doesn't the E start add about 35 pounds realistically to the XR600R after all the added stuff? I think Ill keep my kicky lever! Mine starts first kick every time anyway! Except for once when I flooded it, took three hours to get it fired again.

3 hours!!!!!!!!!!!!!!!!!! did you drown it???

Nah sniper only weighs about 7kg.

On a bike with 18 litre tank not much of an addition really.

More the whizz factor I reckon!!!

Anyone else interested in the detail of how I did it?

Can I get as much info on the parts as possible??Please

Thanx,

No adaptors were used in this project.

split your crankcase install XL600RMG (circa 85-86 era) crankshaft then rebuild motor.

use a XR650L starter clutch bolted to your stock flwyheel.

use XR650L wiring etc.

Use 450X battery under the seat - lop off the front airbox mount to accomodate.

this is seriously a big project and would take me a month to write everything we did down.

it feels good though having worlds only oem XR600 electric start.

I cant tell you how effeciently my bike starts. The electrics are just so ridiculously powerful on this bike.

Yesterday - about 10 degrees celcious - 2 squirts of the FCR, choke, push button, 2 seconds later engine is running and purring.

All oem Honda parts.

What is the difference between XL600R and XL600RMG crankshaft? Only reason I ask is the handa fiche only shows XL600R which I have a 84 XL600R.

I have a 1984 XL600R I have been looking at the honda parst fiche and the 93 XR650L and 84 XL600R use the same crank bearings so I am assuming all I need is the estart from 93 XR650L and use my stock XL600R flywheel on the 93 XR650L starter clutch gear set.
