I'd like some advice concerning the rotor on my 87 paso 750. Got it with 24 000km and has covered since another 15 000. It previously had three owner s so do not know if milage is correct. After a while the gearbox chattered and had it fixed at GPM and few years back the rotor. Fed up, I got meself a Raptor, plastic tank 650 works well but .......

so to the rotor problem

The nut holding the rotor in place lost its threads, the woodruf key widened the rotors key slot due to vibrations. The woodruf key looks like X and I'm afraid not only did I ruin the rotor but also the layshafts woodruf slot. When I insert a new key it wiggles a bit, not much but a bit, also when a new rotor is in place. I do believe when nut is tighten it will no longer wiggle but is it advisable or should I rework/sustite layshaft?

Do I have to substitute rotor only or the whole alternator?

Concerning the 16" road charactaristics with 130/60 I find it consumes front tyre quickly, after afew thousand km it no longer handels like when tyre is new. Living in italy it is hell to change wheel sizes so I was wondering if I could mount a 130/70 Type CBR 900 with satisfactory results.

Thanks

I use in my Paso 88 a Metzeler Sportec M1 in 130-70/16 size. It works very well with a M59 Michelin. Take care with the front mudguard because this tire is higher than 130-60/16.

With Metzeler tire ME, don't forget that some models are a diagonal structur, and Metzeler recommand to use two tire with same structur, not mixe.
