You can always contact him... he is really serious, I should say "they", as they are a team!
In fact I contacted him by eMail before ordering my friend's clutch, insisting to have the very same as the one I ordered him the previous year. I was really upset (for the less) by Golf Cart King & DIY Golf Cart!!! In my eMail, I also indicated him my post where his name was, just a question of correctness...
What is funny is that he answered on the forum instead of sending me an eMail back...
This being said, I love his answer (concerning endless salesmen trying to propose them crap) and it is good to be shared by our community, so...
On the other hand, I am not sure they are too much IT oriented, so if something is not on their web site, IMHO it does not mean they do not carry it or could not help you... *smile
For Yamaha, we have really 2 excellent suppliers: Plowman's and CPP, I hope all brands have their "references" too...
Anyway
