Dusty's Bonneville Scout Build

Post by Dusty-Dave »

This madness started last year when Tom who is a member of our Friday gear head lunch group and who goes to Bonneville most every year to either race or officiate tossed me a copy of last years SCTA rule book and asked if I thought there was a class I thought I could be competitive in. He had underlined a few that he thought I might be interested in considering that most of my bikes are Indians
Image

After reading and rereading the rules book I finally decided this spring that a Bonneville effort would be a good way to spend the next few years of My retirement. After much discussion I am maybe positive that I want to build an AVBF A being a special construction frame which will allow me to get the head stock as low as possible with the 16" rims I chose. The rules allow as small as 15" rims but the cost and availability of tires and rims and the fact that I had a new w speed rated 16" tire made me settle on 16 inches. V is vintage engine produced before 1956 with a 33.33% size advantage given to flatheads. B is blown and F is fuel. Right now the plan is to run Nitrous oxide and alcohol through fogers because of a flatheads notoriously poor breathing even if blown. I started looking for parts this spring Got a pair of 16" 250 Ninga rims and fork and today I won a set of 37 Sport Scout cases. So it will be a 1937 Sport Scout.

Still haven't picked a displacement a 45" stock displacement Scout would run in 500 cc the ABVF record is 73.903 but the 500 cc AVF record is 111.839 so the blown speed should go way up soon and a 57" stroker would run in 650 No record for ABVF but AVF is 144.531. Leaving it a 45 would give me lots more room for piston squirters but would require a pair of std. bore cylinders but I just prefer 57 inchers and the cylinders could be way oversize per the rules.

Main thing I need to find next is a pair of cylinders I would really like to buy new ones but the rules require original cases and cylinders or exact reproductions and only ones I can find so far say improved ports and the rules committee says not no but hell no. I hear that there are exact repros but can’t find anyone selling one that will offer any documentation and at $1500.00 to $2000.00 I sure don’t want a pair of paper weights.

I’ve been promising to start writing this up for a while but having the cases and being able to assign a year to the build finally got me moving. Stay tuned

Got my cases today they are as advertised. Need lots of cleaning. a small weld and a custom sized rocker arm pivot.

Definitely a 37 high performance Scout with a Magneto and the y cylinders and manifold.

Will need a small weld where the cylinder base mates.

Need to extract one broken bolt

All in all a great pair for being 77 years old.

Got the flywheels Truett & Osborn made special for this bike this morning. They are stock stroke with rod bores to take a Sportster rod pin and rods.I have decided that it's going to be a blown fuel 45 so it will run in 500cc AVBF .Still haven't found a front cylinder yet but have a very good rear now.

SELF INTRODUCTION: Hi, bike restorer of 25 years, hoping to step up with an outside the box (for me) build and seeking inspiration, tech assist and bling. Based in Australia I'm a builder of parts as we have few suppliers of non standard parts.

Dam near $500.00 worth of internal engine parts. Soon as I get a set of early Sporty rods the lower end can go together.

Has anyone here had any experience on ruining ceramic ball with steel race bearings? I'm thinking about them for wheel bearings, transmission bearings, supercharger bearings and the alternator bearings. Not gonna run them on the mains in this incarnation. They are pricey as hell but supposed to turn easier and last longer.

Crazy Cats at S&S sent me this super E on the house to help with the Bonneville effort a week or so back.

After I got the free carb from S&S I was feeling high as a kite so I wrote a begging for parts letter to Todd at Jerry Greer's Indian Engineering. Low and behold Shauna sent me one of their excellent clutch kits.

Do we gots any structural engineer types here? I need to know what type of aluminum to buy to machine the heads from. I'm thinking 6061 because of the cost but if there is a real reason to spend more it has to happen.

Found a pair of cases that are repairable in my junk so the backup engine will be a 1936.

Melt down a couple of alloy wheels and CAST your heads ! I aint sure of the content of alloy in car wheels but if it is strong enuff to be safe to drive a ton or more of automobile on it should hold up to being a cylinder head !!

Go to www.alloyavenue.com if you need help !!

The concisus seems to be that 6061 would do but 7075 would be better. I think that maybe I have a lead on some cutoffs at scrap prices. They are going to be 7X8.125X3 so not easy to find. I asked about wheels and was told that wasn't a suitable alloy for heads.
