You guys are so helpful. Great information! I am going to call Gary at custom rewind in Birmingham tomorrow and ask about getting my rotor rewound. In the meantime I will do the testing procedures you recommend because I want to see the current state of the charging system. Hope he is still...
gggGary, I am sooo glad I asked!!! Checked your links and Racetech is out! Any suggestions on a quality rotor source? Found one at Ricks, any thoughts on that one? When assembly time comes, will a drop of Loctite 242 blue be advised on the 2 bolts holding the alternator housing?
Thanks for...
5Twins and gggGary, Hey guys, Well...I opened the left side case and supported the alt housing as you suggested..good tip. Cleaned both rings and everything was looking up...till I took the olm readings on the slip rings of the rotor. Start meter readings 00.2 lead to lead.....ring to ring 01.1...
Thank you 5 twins for your excellent advice and the photo is great! I will do just that. If it turns out the reg/rectifier is bad, I have been looking at the one TC Bros has for my bike at $99. Heard anything about that one, or from another reliable source, I would rather buy one than build one...
Hello everyone! Thank you all so much for the great information I have found on your site. A special thanks to 650Skull for leading me here. Recently got this 81 XS650 SH knowing it has some maintenance issues, but did know it started, ran and idled ok.... but on battery only till I rode it...
Just purchased my first xs650!! I have been admiring the whole series of Yamaha 650's for quite a while and now one is in my garage! It is a 1981 Yamaha SX650 SH. Mileage is 10K. Looks to be stock and for now, except for a few performance upgrades, I will ride it and see what needs to be done.
The throttle is too touchy at low speed in town riding, especially in slow city turns??? Any ideas are appreciated. I can see the chain and rear brake need cleaning/adjusting and after oil, filters, including sump, are soon replaced, will oil the throttle and clutch cables and adjust.
Cleaned it up a bit, took out the plugs and poured some oil in the cylinders and it has compression! But no spark as yet. Downloaded a service manual and will try to rebuild it later so it runs. This little Maytag motor may wind up in a mini bike trike if I can figure out a small belt drive system.
