When I was in KL, I used to do modding for other riders just for fun and also for the sake of promoting the folding bike activities. Then there are many who are from this forum who contact me and wants me to do the mods. I was enthusiastic in the beginning and I only charge them 50 bucks , whether they bring their own parts or they want me to get them from Kimbell Jaya. That's why Jimmy always profited very nominally from my purchase but I did not sell it for more as it was not my vocation.
Here's the lousy part............ although I do not make money from parts, they always do not belief. I can't blame them either as no body beliefs that someone will want to do it just for 50 bucks. Then they will go survey prices and whatsapp me all the time they are visiting LBS for components and finally it came down to me getting it. It makes me feel cheap and feeling like a conman.
Then comes the appointment. I get it done but as you know, it's modding so it's is never perfect at the first time. I will just guide them how to adjust if any problems arises and if they can't do it, call me again. This is where it becomes like a life time warranty. The RD clackles a little, he call me, the gear won't shift smoothly, he calls me etc etc.
Even now, when a forummer ask where can they get their bike painted, I offered to do it with auto paint and lacquer, with decals thrown in. Then I have to dis-assemble the whole bike and as you know, once dis-assemble I have to clean and lubricate everything before I assemble it back after painting. I wanted 350 bucks for the whole process and first he got very interested , then got my contact, whatsapp for my address and then pfbtttt................... went quiet !
Then there was one from Johore, wanted me to do his moddings and I am OK. He said he will send the bike over by courier and I do whatever necessary. Discuss about the groupset prices and everything. Then he wants a copy of my Mycard !

I was like WTF ! and told him to send if you wish and trust but I am OK if he doesn't too.
This is why I stopped doing mods for others. I don't mind guiding and advising but the moment you receive payment for anything, the responsibility perceived by him and me is totally different. I look at it as a token sum for my time and at times some parts that is lying around that I don't use but he perceives it as I am profiting big time from it, like it is my vocation. You know I will be glad that someone wants me to mod and at the same time hang around when I do and learn something from the whole episode.
In fact Jimmy calls me when he can't figure out something and I will drive to his place work with his workers. That was in the beginning and in later stages Kimbell Jaya stocks the parts and starts doing it and I pushed all those who calls me to him. Let him charge them at LBS current prices and let them be responsible for their workmanship.
