First Generation Ascots > The Thumper Years: Stock To Lightly Modified

Considering an Ascot

(1/3) > >>

scott s:
 Hey guys, new member here. Been lurking for a couple of weeks and reading up. A friend has an Ascot that she'll never do anything with and I'm seriously considering grabbing it.
 Done plenty of vintage bike projects over the years, everything from XS650's to a KZ250 to a BUNCH of CB500/550's (my favorites). Plus, had a few more modern bikes, too. I'm a big fan of the Honda middleweights and currently have an '85 VF500F Interceptor and a '73 CB500/550 resto-mod.

 I'll keep bugging my friend until I can get some pics and an answer out of her. In the meantime, I have a few questions:

 * Has swapping out the headlight been covered? I really prefer a round headlight or maybe a number plate type deal. And why in the world did Honda stick the stock light up so high!?

 * What's the O.D. of the stock exhaust pipe where you would bolt on a muffler? What about the O.D. on the header Thumperstuff sells? I have quite a few mufflers in my stash to choose from, just need to see if the I.D./O.D. match or are close enough to make an adapter.

 * I see a lot of people go with the digital dash gauges. Is that just for looks or are there known problems with the gauges?

 * Tell me what to look for when I get a chance to inspect this bike. I know, in general, how to inspect an old bike. But are the FT500 specific things I should look for? I know she said it needs caliper(s), but she couldn't say why. Just that she was told that when she bought it. No biggie, I just did them on the VF500 and they look similar. Any other things to look at particular to this model?

 Thanks, and I hope to be showing off a new purchase soon! (I need another project like I need a hole in the head, but I just can't help myself)

Hi and welcome.
I replaced the headlight on mine (as it had been damaged) with the round one from a modern (watercooled model) CB400/4. Look good and works well.
Gauges are fine, pretty standard Honda stuff and can be repaired easily.
Calipers on any bike will seize if left standing. Are a common size fitted to just about every Honda of the time from XR250 to CB1100R.
The starter secondary shaft bushes fail and allow the gear teeth to get out of alignment. This is heard as a 'grating' noise when trying to start. Easily replaced with caged needle rollers and never again a problem. Check the cam chain and tensioner (it is a 80's Honda) as the teeth of the rachet in the tensioner wear down and allow the tension to slip. Easily replaced without taking engine from frame.
Other wise they are a good thing (in my mind) so go enjoy the ride.

 Did you re-use the stock headlight ears?

It has been a while since I did my headlight swap, but I don't think the original headlight mounts will work very well. Think that was the only potentially difficulty, finding suitable mounts. I ended up buying a new headlight, mounts & turn signals from EMGO like this one: http://www.speedmotoco.com/product-p/smc.404.mofo.htm

I ordered it with black turn signal bodies. The mounting brackets just make contact with the fuel tank at full turn lock to lock. You could remove a bit of material for clearance. I just avoid turning the bars that far. Avoid the mounting brackets that look like they are made from thin stamped steel if you ride at night much. Sometimes the headlight will vibrate too much.

I think the reason that some exchange the gauges for digitals is usually due to either crash damage, the desire for something smaller, or they want more information available.

Chances are you will need a new battery. Do yourself a favor & buy a good one. I use & recommend the sealed AGM type of battery. Preferably made in the USA. Check out Batteries Plus. The FT Ascot requires a stout battery & the cheap Chinese wet-cell lead & acid batteries usually don't last very long. Plus they vent corrosive gasses onto the bike causing corrosion.

There are not very many exhaust header & muffler options available. The EMGO universal reverse megaphone will work. They come with 3 adapter collars to mate up the pipe diameter. If you go that route, buy the two-piece unit so you can remove the core & re-pack it with a better silencing material.

Make sure you check out the topics at the top of the Tech section: http://ascot500.com/index.php?board=11.0

Good luck
J.

Yes, just needed longer bolts.
