GL 1100 alt conversion!!
Hi guys, been somewhat of a long time but got a pulley from Don P. for a conversion! There's a guy over on S.S site that I'm going to use his idea plus give him credit, but just wanted to share this will happen in the near future!!

Hey Bob.... Best wishes on the 1100 conversion. :YMPEACE: Make sure you share lot's of pictures and instructions while doing the change-over! I may be helping / doing an 1100 this summer on a friends bike who's charging system got weak last year. I'm wondering what the conversion differences are between the 1100 and the 1200.

Hi Adam, nice ST 8) ! The voltage he's getting now at about 1300rpm is 13.5 running a 1 to 1 ratio!! He's using a 2.5" pulley but suggests using a 3.5", some are using a 4" pulley. Mine will be a 3.5 when I do mine but claims this size should be better at the lower rpm. Since I have a Carb Conversion and idle about 1100rpm, this should work good. He did his conversion on a full dresser, with little to none fabricating. I think what really helps, is the size of the alternator one chooses! Here's the link showing how his is done, <!-- m --><a class="postlink" href="http://www.goldwingfacts.com/forums/forum1/93366.html">http://www.goldwingfacts.com/forums/forum1/93366.html</a><!-- m --> hope it will help!! Time for ~O) !!! Later :YMCOWBOY: , Bob

Adam, the alternator I have coming is a Ultra Mini Denso rebuilt off Flea Bay and the guy was nice enough to change out the v-pulley to a 3-groove Dons' P. pulley!! So the size of the alt. will ( I think ) make a difference!! Bob

For you guys converting the 1100, Dan Filipi used an alternator from a garden tractor (Kubota?) and it fit in there perfectly and he say's it works great. He's a member of this site so do a search and look him up for install advice. Here's Dan site: <!-- m --><a class="postlink" href="http://classicgoldwings.com">http://classicgoldwings.com</a><!-- m -->

Thanks for the link Vic. You can never have too much information!

I was doing some preliminary re-search, and was looking at that alt. you had mentioned. Also fits a John Deere Gator. Puts out around 40 amps. More than enough for a bone stock 1100....

Thanks Vic, hey as long as it works to your need, fits the way you want it Great!! I think thats what's so cool about these conversions, you have a wide variety to choose from. I'll have to check that alternator out!! But not to change anyones mind, but if it's the one conversion he had to extend the top and bottom radiator inlets and outlets. Not against his conversion but keep in mind this conversion I will be using only moves out the bottom of radiator and reajusting the lower & upper fairing brackets. There's always a BUT,.... is the stinking fan,.... looking at mine today, the OEM sticks out so dang far! To resolve this I will use a thinner electric fan, not sure which one yet but not hard!! :YMCOWBOY: Bob

If there is enough room I might be tempted to use two seven inch fans side by side mounted as high as possible with a custom bracket in the hope that I would have enough clearance from the crank pulley so that the bottom of the rad would not have to be pushed forward, but, it would be an experiment and only testing would prove the effiency of that setup because the CFM of those fans are marginal. 10 inch might be better in the end.

Mourning ~O) Vic, Just from looking at the OEM fan, it seems the biggest factor is (I think) the rear of the fan motor. The guys' plan that I'm kinda following used a different fan that looked smaller but put it up way high. I forget but I think it's from a Suzuki :-\ !! And also noticed while shopping for a fan, there are alot of differances in the cfms!! Need more ~O) ~O) !!! Later :YMCOWBOY: Bob

Now that I got my 2nd. wind :lol: , I'll try this again (lost the first post) :-W !! Today while on the net, I looked up at I think :-the Honda Direct site, the size of pulley bolts. What I found was the Gl1000 have a 10mm bolt and the 1980 1100 and 1200s' have a 12mm bolt. The signifignace of this, Don's Poorboy 3.5" pulley is a 12mm and there is also an attempt over at Classic Goldwing to make a 4" pulley,...12mm. I know this is a 1200 site but just in case,... you where going to make or purchase one, there is a difference in bolt size :YMPEACE: !! And I sure you would what the right size for the right year :d ! Vic we where talking in the post above about CFMs, would it be better to get one at 2300cfms or 2 at 1550 cfms,.....just trying to get some opinions before the conversion!! :YMCOWBOY: Later Bob

Just an update,.... I started on the alternator conversion. It took me 3hours to cut that hole in the cover :-W . I must have taken those covers off 6 times and on more just to get a good fit for the pulley!! But,......the stinking teeth broke on the right side causing an oblong hole. :YMSIGH: So I did the rest of project wth a dremel, trying for a better fit. The right side I put some JB WELD to fix the goof I made, then once dried, I'll reshape it for a better fit :d !! Once that's done, if the wife doesn't have too much running for us tomorrow:lol: , I'll start on the alternator bracket!! So Later :YMCOWBOY: Bob
