I have just got off the phone with Carol Gash (lovely lass) who tells me my insurance will be £300 less if I put an original spec 1000cc engine back on my J reg gs(it was changed to an 800 by a previous owner). Is this a relatively easy job for a beginner?
Does anyone have an engine of appropriate spec that they might want to swop for any of the following:

RT frame with v5 (good condition),

r100 engine with carbs and gearbox(monolever version with metal air box),

or the 800 coming off my gs.

I'm told the 80 is a more reliable engine is there much truth in this?

It has one

Just to avoid oil cooler conversation it was never taken off.

I would try some other insurance companies. A £300 reduction for putting a more powerful engine in? They're taking the piss I reckon.
 
more bits

I did shop around. I think the issue is that the computers do the thinking and the computer says no. Because the engine isn't 'standard' everyone seems to consider it a non standard modification.
If I'm completly honest I'm quite happy for an excuse to get a bigger engine.

Just thought to add that the R1000 engine has loom, front forks and few other odds and ends with it. I'll put everything I've got (with photo's) in the for sale section next week to try and raise funds or for swops.
 
parry

If you already have a 1000cc engine why are you selling it to buy another?

The insurance company say it has to be the same spec as the original. The spare engine I have is an early one, I was off the understanding that they are a little different. I also have too much crap in the garage and would prefer to find a newer engine if pos. If the general consensus is that this is pointless, I wouldn't be adverse to telling the insurance company what they want to hear.
 
If it's a monolever R100 Engine (86 onwards) it should be pretty much the same spec as the 100 GS engine apart from having 32mm carbs of course but non uk GS bikes also had 32mm carbs. Do you know what year the engine is?

It's the twin shock engines that had the higher power output
 
Just stick the 1000cc barrels and pistons on the 800cc engine. Why change the whole engine.
 
not sure

Will look up engine number tomorrow night.
 
I think you're not telling us s'thing....no insurance company would ask this sort of thing

UNLESS you are asking for some sort of specialised classic agreed value insurance.


it doesn't make sense.

just tell them its exactly as it says on the logbook - a bmw 1000 - they aren't going to check are they ?


some people worry too much
 
I can't understand CN charging that sort of money for an R80 .......

I only paid £430 for my multi bike policy fully comp - & thats with 7 bikes on it, including a couple of group 16 ones ....

When I added me R80GS, they only wanted an extra £30.....& half of that was for admin costs !
 
You're a cynical bunch of ....

When I bought the bike the log book said the bike was an R100gs with an R80 put on/in at a later date. I made the mistake of telling the insurance company this because I assumed it would make the insurance less, not more (especially as I am/was new to motorbikes).

If you don't believe me ring up your insurer and tell them you are thinking of putting an r80 on your r100 and see what they say. I would be interested to hear what there response is.

I think the biggest problem you have Oggy, is that you are a relatively new rider and at the same time still quite young. This being the case you are going to get screwed whatever.

Why don't you call the insurance companies and tell them the original engine has now been refitted, quoting the 100GS's engine number that I assume is still on the reg docs :nenau

BTW Have you tried calling the BMW insurance people at Devitt? They offer BMW specific insurance so might well be able to help you out.

But I will learn

Thankyou Val, I'm actual quite happy about the idea of getting a bigger engine. With the change, the insurance will only be around the 350 mark which given my age and inexperience is not that much of an issue.

I'm just looking to do a 'proper job' when it comes to changing it over. I have lots of bits to swop so was looking to find a cheap way of getting the right engine and doing a good job of it. Was just hoping for a bit of guidance given my lack of mechanical ability. (other than 'don't do it if you don't know what you're doing') If people think swapping the barrels and pistons over is the right approach I'm happy to give that a go. I'm assuming I'd also have to change the exhaust to a wider diameter.
