Sorry for the delay Gordo,,, your moke will be right to pick up sat Arvo

& just to show the level of detail that my build guide is ,,, it`s quite a mammoth production, but is very easy to read (all be it quite a lot of reading) & hopefully you will find it amusing as well,,,, but here`s an example of the "Step-By-Step" ---"In-detail" procedure i`m giving to the people













This is just an example & should show the amount of time & dedication i am putting into this project,,, it`s not just some "half arsed" Chuck together, leaving you wanting for detailed info,,, this build guide is so comprehensive in every way shape & form that there is very very little left to the imagination,,, nearly every single procedure is written about, photo-ed & even video-ed during the build of both small bore & big bore engines with my helmet cam,,, serious!!!!,,, the entire process from start to finish is listed & is basically "no stone un-turned" type of guide,,, if you have a question about this conversion, then the answer is in this guide & not only typed but pics & vids of it too



Again i must take this opportunity to appologise for the length of time it`s taken me to finish this, I did say a "month or so" whn i finally finished the kits but as you may be able to see & understand,,, i`m not doing things by halves & all this takes time

I reckon The build guide alone is worth the cost of the actuall conversion kit I wish it wasn`t but it works out "Time-wise" alone, that it`s cost me more than that to produce

Oh,,, & photos just don`t do this conversion justice so please realise that the pics are barely scratching the surface of the reality of the detail

I`ve now made 2x Small bore engines (done 2 different ways) & both are basically ready to be put together now,,, But i still recomend you go for a 1275 instead,,, small bore Twinkys are a worker, no drama now we`ve done the "R&D",,, just that for the extra stuff around i believe a big bore is still better value for money.


That said,,, i just can`t wait to take my small bore Twinky for a spin

so they are not running yet Matt? i could still be the first with a running 998 based small bore!! I think mine is done different to yours as well.

I fitted a 16v head ontop my 998 block the other day and it doesnt seem to bad a fit!! still going 8v on this one though.

Matt,

One Q: what is the possibility of overbore with the twinky, and how far can you go e.g. 1380, 1410???

miniboo,,, not yet but not too far away, i`m going to have to stop on them for a few weeks & spend some time on the turbo twinky moke, but after that i`ll have my little roady 8V 998 running on a cheapo carb & dizzy

Tricky,,, the very first twinky i set up was a 1415cc stroker with injected 16v & i`m in the process of fitting up my old 1510 roady with a 16V too,,, preparations for the transformation have already begun on that one,,, just that as usual my own performance play time is restricted for the sake of the greater twinky comunity Matt the Marta bring out the violins hey?

Kev,,, i told you not to ask me,,, i don`t need to be reminded how stupidly expensive that K1200 head was,,, i really didn`t "NEED" it,,, but just figured that i might as well & i hadn`t seen another one for sale,,, havn`t even found one to look at in real life

& the K1200 is much bigger throttle bodies,,, much bigger ports, better prot angles/shapes,,, much bigger valves & much bigger cams

Much bigger in my books is much better,,, Just ask any chick

But especially when it comes to BMW motobike cyl head engineering

Dam it i just wanted it,,, you`ve bought stuff you didn`t really need right??? You just "Wanted" it yeah???

well,,, there goes my christmas presents money

Matt,

Is it the 1200GT, RS, S ?
Are the heads all the same on the different bikes? I would assume not but who knows with BMW

Kenno,,, i`ll happilly take you for a spin in it mate, no problem there

Pete,,, it`s the RS version of the K1200, & as far as i`ve been led to believe the castings & valves are the same throughout the 1200 range & just the cams change,,, but i havn`t seen them all myself personally, just what i`ve heard.

Hi Matt

Will your build guide be available for sale with out a kit

Also when did the k100 heads change to unleaded valve seats

Ta

Bernard

Pretty sure, as they are ally heads they all have hardened seats so unleaded is not a prob whatever the age. i stand prepared to be corrected though.....

_________________
1062cc k100 8v in the works......

Bernard,,, i`m thinking about that,,, But i`m not sure what would be a fair price to charge if i did sell them,,, i know how much time i`ve spent but i certainly can`t charge that out at an hourly rate,,, no one could afford it but at the same time i wouldn`t want to give them away either, effectively shooting myself in the foot (again) However, i have had other people suggest that maybe the people who buy them could then get that price discounted off the price of the conversion kit if they did buy one & i think that`s quite a fair proposition,,, but it`s really back to how much should i charge???

& the unleaded question,,, well they (the 8v heads) actually became unleaded at around 1985 ,,, but there are many people who will suggest that they`re all unleaded (miniboo & many others,,, sorry miniboo ) but they All really were "Tough" valve seats & can run on unleaded anyway,,, just that they weren`t "Truely" unleaded until 1985.... You can check what head you have by popping out your exhaust valves & if you have a groove around the outside of the valve seat insert then you have an unleaded head,,, if they don`t have the groove then they`re pre-unleaded heads,,, Engine numbers & frame numbers can be checked to confirm,,, but if you only have the haed & no engine & no bike frame then the only way to tell is by the exhaust valve seat insert grooves ...But as i`ve said,,, either way they can run unleaded because they`re all "REALLY" Ph`kn tough valve seats anyway

However i`m pretty sure that "all" the 16v heads were unleaded.

But,,,,, Hhhhmmmmm,,,, how much to charge for the build guide on it`s own????

how about $1250, and you get a free conversion kit?

people may be asking for the build guide pre-purchase so they can see exactly what's involved, without the "no worries" and "easy peasy"s from your explanations on here - so maybe a cut down version without the detail could be available pre-sale, and the full version provided with the kit...

just thinking out loud
