Yamaha TRX850 Enthusiasts Forum

Ok guys , I am looking to change the coils on my Rex as the the performance is very stuttery between 2000-4000 rpm . I think the coils are one their way out , they are 20 years old ! Any one got experience with after market upgrade coils eg Dynatek . Any suggestions as to what would work well ? Thanks in advance

I´ve run the Dyna for at least 5-6 years now...no hickups!

I'd be looking at emulsion tubes causing that problem. You can check the internal resistance of the coils to see how they are performing.

Did you get my PM regarding the fairing??

Thanks guys I have some FCR41s on their way to me so see how they go , Thanks Killerwhale that's what I was thinking Dyna coils.
Dandy please accept my apologies things went Pete Tong at my end , I got sorted out by a mate who used to have a rex and had some spares.

Ok, thanks
