Wax up the Belstaff. No worries. :D

Belstaff was good in its day but I wouldn't buy (jacket or trousers) now.

It also became trendy so the price shot up!

TRIALMASTER PRO48 JACKET
In Black Tumbled Waxed Cotton
Sale Price £625 :confused:


My first Trialmaster jacket cost me £10.00
Modern textile motorcycle clothing is much improved compared to the old Belstaff clothing.

Wow. That's spendy! Mine was $50 US for jacket/over pants (second hand) in 1981-82. Doesn't fit quite as well as it used to for some reason....o_O!

Getting way off topic here. Signing out. :) ~998cc

I heard some years ago that there was a difference in the shape of the steel Interstate tanks from 72-74 vs the shape of the tank for the ‘75 MKIII. Is this correct? If so, will an earlier tank for my MKIII? If so, will there be an issue with the MKIII seat not fitting correctly or leaving a gap?

Yes there will be an issue with proper seat fitting right up close to the tank but not quite touching.That is the goal.
 
Not sure about the mk3 specific questions, but IIRC there are 3 or four different versions of the steel Interstate tanks.

Earlier ones are slightly wider at the rear and have no baffles, and a slightly larger capacity. I have seen people having issues with tanks also clearing the coil mounting brackets as well, so there may be models with narrower tunnels.

I would ping your question to Matt at CNW. He probably has way more experience with them and seat fitment than most.
 
I just received a set of steel side covers from royal chopper for a
850 commando...they’re horribly wrong....looked great until it came time to mount them ? I paid 139 dollars plus shipping,so not a terrible hit....cheap lesson learned too......buyer beware ! I also was on a multi-year search...quest to find a good steel I-state tank...I finally found a VG condition steel tank W-locking fuel cap and fiberglass I-state side covers on this forum for 1500 bucks..... I snatched them up and have been very happy with this purchase ever since
Bottom line... IMHO....stay away from royal chopper AND keep looking,your I-state tank IS out there and it’ll be worth the wait
 
Interstate tank
 
I have a steel 74 and mk3 interstate tank and there are construction differences. Mk3 tank is baffeled and appears a little smaller. I have the 74 tank on a 72 combat and it fits fine. Like everything else on a norton some tank fitment will be required.

For the record, are they I-State or Roadster panels.
 
If anyone has fit an earlier style Interstate tank on a MKIII and had some fitting issues. I would like to hear from you. I would like to know what specific issues there may be. Also, if it is possible that one of the earlier style tanks simply will not work on the MKIII. Hoping all can be made to work..??
 
I can't speak as to the Mk3 tanks. I've never even stood next to a Mk3! Amazing really but that's how it goes. However I owned a '74 Mk2 Interstate that I bought in 1976 which had a steel tank, with no baffles and fiberglass side panels. It came from the dealer like that I am sure. I currently have a 1972 bitza with a steel Interstate tank that has no baffles and has fiberglass side covers. I also have a steel interstate tank that is not mounted that looks exactly like the one on my '72, it also has no baffles.

As a result I am thinking that none of the tanks had baffles prior to the Mk3, but also can't speak on fiberglass Interstate tanks as I've never looked inside one. I realize that my sampling is random and small. As for the side covers, I never knew you could buy them in steel until I saw someone in this forum looking for them. I have no clue as to how the fiberglass vs steel sidecover thing works.

I have a 70' commando. I have no clue what "MK" it is... It was originally a roadster. I bought an ebay interstate tank made in india. I had issues fitting the tank because the 70's yoke offset is less than later models. With the tank studs all the way to the back of the holes that support the front, It was too close to the yoke for my liking,... So, here's what I did...

I took my cut off wheel and opened the circular holes in the wings of the tank support brackets towards the rear direction, then I did the same surgery to some giant sized thick washers. Then I got my welder buddy to weld the washers to the brackets, so instead of a circular hole shape for the tank studs in the support wings, I have an elongated oval shaped holes so I can pull the tank back wards. It helps with my low, short bars and smaller offset yoke to give me a little more space between the bars and the tank.

I did one other modification too. I had my welder add 1/4" of metal to each steering stop to limit the swing of my yokes, so my switchblocks wouldn't bang into my interstate tank...
