Hi Who:
I really hate to rain on your parade. I really do. Before you spend any money on an 01 you need to read every post ever written about 01's.
If you are not worried about trying to get it to start on the button then you will be happy. An 01 can be successfully kick started. Just make sure the kick start activated decompression system is intact and in good working order. I would get Taffmeisters most up to date jetting kit and maybe the dual valve spring kit and be done.
Trying to get an 01 it to e-start is nearly impossible. The first major hurdle you will be up against is that some of the internal gears have a different tooth profile than the late 02-08's thereby causing too much drag on the motor. You would need to change the:
Counter balancer, balance drive shaft, drive gears on balancer drive shaft and crank shaft and also the outer clutch basket.
With that being said Taffmeisters has been able to get an 01 to start on the button without internal gear changes by doing the following:
"1)beefy starter motor - extra strong anyway!
2) CTZ7s or YTZ7s battery
3) repair the starter gears which would normally be a stronger sprague bearing spring on either the same bearing or, if the teeth are flattening off; a new sprague bearing. even slightly flattened off, the 400-501s will start if all else is well.
4) iridium spark plug like the IXU24 denso plug or the DCPR8EIX by NGK
5) later 08 cam on the 2001-2003 650s, the others don't have to worry so much. this has poor cylinder filling when cranking (which is good news) and is easier for the valve springs (less resistence).
60 fit the later auto decomp and a stronger spring or re-tension the original. this is thee Number 1 thing to do....decomping!!!!
7) DVSK like the ones I sell or KTM. the Kibblewhites are too soft for the 400-501 but OK just about for the 650. Dual valve spring kit.
6a) face the inlets especially, cut the valve seasts, square the stems etc. look out for cupped tappet pads, cam follower bearings clonking, cams that are spalling.
correct ignition timing marking a new white line for TDC and using a timing strobe light.
9) major work with the carb. So new atomiser, needle, O rings, fuel valve, smaller choke jet, change the slide to one we sell, change the PJ, set the float height, fit a variable choke up to the handlebars.
9a) you can't have a cruddy air filter = get a new one!
10) valve clearances are 1/6th of a turn. if you stand by the back wheel, you should just make out the mechanic making a 'tic-tic' as they "morse code" the rocker arm.
as a nice touch, use the 2004 solenoid mounting bracket and fit the solenoid that's out on the end of the solenoid infield under the air boot for cleaner lines.
with the slide change above, the dell orto is back in the game. however, the keihin is simply a better carb."
If you wanted a second generation Berg then you should have looked for an 04-08 model as these have the bugs worked out.
Hopefully you did not pay too much for it. If it were me I would concentrate on dialing in the carb and ignition timing and leaving the e-start be for awhile.
The next upgrade may be the 04-08 camshaft and autodecompression device.
You will probably want to replace the timing chain and or at least the camshaft follower bearings right away as these can be a failure ready to happen due to the severity of the cam ramp up and pin diameter of the CFB's (both of which have been updated on 04-08 models).
When you ride it for the first time you will immediately notice that as soon as you crack the throttle it wants to abruptly lurch forward. This is the cam. If you replace with the 04-08 cam it smooths things out nicely.
If you just don't want to deal with an 01 then there is the option of dropping it off at Ned's in Cottonwood Arizona. Its the Official 01 Repository. Just throw it over the fence in his back yard. If you sign over the title to him he will give you a beer.
