Well I have more info I broke out the impact wrench and pulled off the variator and the clutch. The good news is nothing appears to have broken and there wasn't any belt debris, that is the good news. The bad news is the roller weights do appear to have a lot of wear they are worn flat in several spots so those are going to need to be replaced. I also found this:



as you can see the belt is not getting all the way to the top of ether the variator or the fan and there is a big difference between the two as you can see below:



that is the variator about 5mm from the top

and the fan



as you can see is about 10mm from the top

I think I might have found the cause of the lack of travel though
this is a shot of the pins on back of the variator that hold the plate in place.



as you can see they are badly worn to the point that the plate is catching and can't travel any further. I think i am going to be getting a new variator in addition to the belt.

The the variator is about 10mm smaller that the fan and from other posts it sounds like that will rob me of top end, am I reading that right?

I also checked the roller weights all exactly 13 grams.

So here is what I think I need to do. I need to replace the variator for sure and I think I want to go with a "performance variator" that is the same diameter as the fan. With it get 3 sets of weights in 12, 13, 14. The idea being 13 might be the right size but the travel is being restricted by both the size mismatch and the rather nasty wear on the pins. I don't want to go a lot heavier as I am pretty happy with the acceleration right now but if I could get about another 4-5 MPH on the top it would be great.

Does that sound about right or has the brake cleaner gone to my head and I am missing something important...



an thoughts or ideas would be helpful.

So this one was sold under the Baron brand name and has the name "speedster" on the side but was built by JMstar who I think sells most of there stuff under the Jonway name now. They still sell this one it is called the BAS Pagoda and comes in 150 and 250.

This one is just a 150 and with all the weight from the extra plastic it tops out on the flat at around 52 Mph. I have already posted to the tech forum and gotten some great input on tunning it a bit to get a few more MPH out of it without burning the engine up.

I completely lucked out I wasn't even looking for something this cool I was looking for anything under $1000 (the budget the boss gave me). A friend said he had one he wasn't using anymore and if I wanted it he would be willing to sell. So I went over to take a look and this is what I found gathering dust in his garage. needles to say I bought it on the spot. He had purchased it from the original owner who had purchased it from an importer. It is a 2006 and I bought it with about 3600 miles. I have had it for about 2.5 weeks and it has around 4000 on it already ;D

one of my student workers (I work at a university) who is a ECE major when he saw it his first comment was "that is completely nerdtastic" and the term sort of stuck :-)
I guess it is that I work in IT and I am sort of a geek.

Thanks for your clear explanations Cruiser that answers my question of which to do needle adjustment or jets. If I understand you correctly start with jet and then adjust the needle if it still needs it.
What is the difference between a slider weight and the standard roller weights?

Thanks for the enthusiastic welcome Bong, this has been the best place I have found and great bunch of folks who know there scooters.

I was in London (UK) a few years back and saw a few of them they were mostly BMW of course but still it was wild to see and businessmen running around in there suits on scooters with roofs. this one is built by JMStar and was sold under the Barron nameplate. They (JMstar) still sell it under the johnway namebadge as the BAS Pagoda in a 150 and 250. I have only seen 1 other one, in Seattle just a glimpse on one of the bridges in the pouring rain of course. It works really well you really do stay dry and living in western OR it rains a lot. The only downside is the extra weight and in a crosswind it can get a little squirrrely but you can take it down and it folds into the trunk. I'll take some action shots and post them to the pictures section.
